Let’s keep it simple. Install cold air intake, install performance headers, either straight pipe your exhaust or install performance exhaust, and tune your car. Do all of that and you will have a car with more horsepower

[@averyalexander2303]

His method is better, he explained how it could increase power and what to look for. Also, his advice applies to all vehicles. A dyno test would only apply to one vehicle and intake combination, which is all over KZbin anyways. Just search for "cold air intake dyno" and you will find plenty of dyno tests, all with different results. A dyno test is useless unless you happen to have that exact same type of vehicle and you are planning on getting an intake exactly like the one tested, other than that its useless since results from one make and model of vehicle can not be accurately extrapolated to others, the results will vary dramatically depending on the intake, the vehicle the intake is installed on, and what other mods that vehicle has.

Be careful with K and n filters, there prone to getting really dirty and can dirty up your engine which can kill your car

[@vikassm]

@@herniagaming Absolutely true. K&Ns are designed more like a sieve than like a filter, so yeah, the engine runs faster and also dies faster 😂 Particulate/dust filtration is barely acceptable on a new or freshly oiled, filter, but drops pretty drastically with just a few hundred miles on the odo. Clean your K&Ns every 2-5 thousand miles depending on the dust in your driving environment. None of this is is a concern if longevity isn't, er, a concern😅

[@davva360]

In my experience they can make a difference but it is small. To really benefit you need to also upgrade the exhaust and then reprogram the ECU. Just replacing the air intake won't make much difference.

[@klwthe3rd]

Yeah I'm surprised R & W didn't talk about the need to reprogram the ECU to really take advantage of the gains.

[@FCT8306onTwoWheels]

True. Modern cars will simply dump more fuel into engine and nothing more because so much more air is coming through. And that will be at all speeds from 0 mph and up. Tried a K&N Typhoon system and it made the mpgs drop to half with normal driving. Drove slower and idled rough. Got my money back.

[@zandern9489]

Having been in the ‘mod’ game for many years I agree with you on many points. It really depends on the car, the application, and how well executed. Recently though I stumbled on an ancient article 😂 done in the ‘80s about just this topic done by some engineers. One thing to note was that auto manufacturers didn’t just make the air boxes with resonators to kill noise- it was also to keep intake system pressurized, so air was constantly on demand . Ever notice on some cars with SRIS (short ram intake system) it feels a bit ‘boggish’ when first going? The intake system isn’t pressurized and needs to ‘suck’ air in, which we all love that sound, but your actually losing low end torque too, it’s bogging out. Super rich on low rpms, then really lean with higher rpms, which is good if tuned properly, but can prematurely wear your engine. And ya, usually the factory system is colder than an aftermarket 90% of the time. (Depends on the aftermarket system though) I chose to go with a high flow filter in stock system since my old arse intake doesn’t use the typical AIT filament sensor, which yes, the oil on a wet filter can ruin. If I had a newer car, I’d run a dry filter in stock location and open up the exhaust piping from the down pipe back to no more than 2.25” on a NA car. On turbo, bigger downpipe and exhaust is crucial for spoolup, but that’s a whole other topic😂 Nice vid!

[@decayofalberta1520]

Great video, it explained a lot. I always wonder the different between the intakes systems and cold air set up.

[@khronin]

I am on the fence about getting a cold air intake.Having gone to the track many times in my life--from stock cars to full blown race cars--90% or more had cold air intakes.Also--when I walked around and looked at factory race cars--they also all had cold air intakes.I wish there was just some honesty about this when you ask your local dealer about a cold air intake and you can literally get a different answer from all of them.The cold air intakes also on factory race cars--looked very similar to what you could buy for your stock car.BMW--M--AMG--Ford Racing-Honda and Acura racing--Porsche--all of them had intakes.The manufacturers need to just be honest-The computers--and I was told this by engineers at the track--all can instantly adjust for air and if you give them more air at a higher cooler rate--it will generate extra power.I mean a modern car has to run in Alaska--and in death valley--huge temp and air density differences.Some dealerships also will put K & N air filters on their cars--and some high performance--like saleen--will even put cold air intakes on their cars that are still under factory warranty--yet the service department will say it is useless--void the warranty--etc.i doubt all these race teams would do this--but the car companies need to get service advisors and this type of mod on the same page.

[@sourwords1808]

I have a turbo diesel. Once i installed the CAI i noticed it's more responsive from stand still take off. It used to bottom out most of the time before the power delivery. Now that it's got CAI it's less laggy and more punchy. Now I'm not saying it makes noticable hp gains but a definite difference picking up speed more fluently.

[@skymonkey30]

Cold air intakes and Short Ram intakes by design do potentially perform better if your air box is very restrictive. This is dependent on the design of said vehicle. Not all vehicles are the same. The only way to really get cold air benefits on a short ram intake is by customizing the front grill so as you get up to speed air can blow directly through, onto the filter itself. Personally I like this method better than a long tubed cold air intake because the cold air intakes even though they are placed farther away, the pipes still get very hot all the way up top to bottom so the main benefit from a cold air intake is that it runs more efficiently but still doesn't guarantee much colder air. If you want the coldest air possible you have to have that filter sticking either outside the hood or very low to the ground where it's nearly scraping (Bad for Rainy days) for air to blow directly on it. True cold air comes from air blowing right onto the filter. Other things to consider is use some heat resistant tubing for your piping as most aluminum can get very hot in summer which can almost guarantee hot air regardless of placement. How you configure your setup is really what counts. For maximum efficiency it takes some custom work if you want the coolest air for your intake. My setup I chose is a short ram but it doesn't go directly across. It hangs more down, plus I added my own custom heat shield and I cut a portion of plastic off the front just behind the front grill so air can flow through and blow directly onto the filter itself as you get more speed. Overall I really liked my setup as I live in an area where it gets really hot in summer time. Weather is also a huge factor. If you were to compare the performance of a regular Short Ram Intake in cold weather vs a Cold Air Intake used during a Hot Summer. The short Ram would more likely perform better. Customizing to get the most out of your setup is the best thing you can do if you want max performance.

[@yalsaied]

Many thanks as always, lots of good info.

[@tonybundy8185]

I like intake noise!

[@andrewchristianson2086]

I found on my 2014 Mustang the CAI doesn't work as good as the stock airbox until you tightly cover the filter and basin. Therefore air is forced into the system instead of much being wasted into the engine bay. Once you do that you can definitely feel the difference B)

[@illx2367]

On my '12 i4 accord I removed the pre induction tube silencer and added a drop in filter. These accords take air flow very well and I have way better response and sounds great on the crossover from 2nd to 3rd. Slightly modded air box but I love it. Rather tan spending 250 or 300 for a brand name CAI

FINALLY, someone explaining the reality of so called "cold air intakes." Unless it is DUCTING air from outside of the engine compartment, like the stock system does, it is NOT a "cold air" intake. I see so many younger people putting a system on their car so that the engine draws in hot air, because their friends, people on KZbin, and the marketing companies told them that the system draws in "cold air" by the very name of the kit, and these same people seem to totally ignore common sense that tells them this is not true. Thank you for explaining it to them.

[@tommyj19751]

Put one on my 4.3 blazer. Also have a cat delete. Took the time to use hp tuners to adjust the ve tables and maf calibration. It made a great deal of improvement in my throttle response. Also gave the engine a nice growl under the hood. As OEM air boxes are designed for noise reduction.

Great marketing lie. You are usually removing the factory cold air intake, then adding a hot air intake that’s just called a cold air intake. All four of my vehicles get air from the grill or behind the fender with the stock setup(cold air). Why would you want hot air from the engine bay? Less power more noise. The days of poor factory design intakes are long gone.

I use a cold air intake on my 2006 Focus, not because I was looking for power, but because the car's air filter was supposed to be "Lifetime" (and obviously it wasn't) and it was going to be $800 to replace the filter because the entire system is sealed, or $200 for a cold air intake. That being said, I still have the same MPG as before because I monitored it for the fun of it, pre and post CAI. Been using that system now for more than 3 years without a single problem

I put on a CAI that goes beneath the engine for my sports car...noticed a huge power/acceleration increase immediately. It even has a better exhaust note. I have to keep the OEM intake because the replacement CAI won't pass SMOG tests in Ca. So, every two years the car feels like it's driving through mud, towing a train...at least until the SMOG test is over.

they pass tooooo much dirt in exchange for a couple horsepower at 6,000 rpm. Clean and reoil every 5,000 miles. Then 200 miles later clean the oil off your masd aur meter. NOBODY DOES IT

[@Willadin]

@@hotrodray6802 I've been using an AEM dry flow filter for a year now and so far its okay. I just dust it off with a blower every 2 weeks and wash clean with their filter cleaner every 5000km or 3 months, no need to oil unlike K&N. I clean my maf sensor and throttle body yearly as part of maintenance.

[@Sandy-oy2lr]

Some engines won't respond at all unless reprogrammed to take advantage of the greater, cooler airflow. Some systems are more forgiving and may actually automatically compensate. Whereas others may throw a code. Or the engine doesn't run right. And another BIG issue is hydro locking if the aftermarket didn't design in enough splash guarding. Manufacturers spend thousands of hours and millions of $$ to design a lot of these intake systems to do everything everywhere, no matter what the weather throws at one.

[@TonyRomeNewMoney]

Excellent video. It’s critical to isolate the filter side of the cold air intake. To do this, you’ll have to make modifications to the car including cutting holes in sheet metal.

[@jhfjhfkf]

nice intro about people being hospitalized, you had me paying attention like "whaaaat cold air intake taking people to the hospital?", funny intro!

[@mungewell]

Another issue that you don't mention is how the stock ECU measures the air taken into the engine. The factory MAF/MAP sensor may be 'confused' by a less restrictive/different intake. The stock ECU will be optimized for a number of factors, not necessarily just power. For your BiTurbo you may be better off spending money on tuning, rather than upgrading physical parts which may (or may not) make a power difference.

[@shitthebed7939]

I put the cold air intake on my 2013 Ram, along with headers and intake spacer. I know it help keep the airflow cooler. Along with 190 degree thermostat, you really have to work to get the oil temp much above 200. I've done some heavy towing with it and wouldn't change a thing.

[@James-ns6jm]

Something like a K&N drop in panel filter will work out much better. Seen as you was considering cold air intakes which use the same or less restrictive filtration anyway. Sometimes you can modify your air box from the bottom. Cutting a circle out of it and attaching piping to the bottom and feeding it to the bottom part of your car where the grill is. Then it feeds even more cold air when needed. This would be much better solution than a cone shaped or something similar cold air intake.

[@skippy2987]

Something tells me you both haven't measured intake restriction before and haven't thought about how it affects the operation of a turbo engine. Your Audi is particularly interesting in that it controls boost to maintain a set air mass flow target rather than a boost pressure. I'm happy to go into the maths of it if you want, but the short version is that less intake restriction lowers throttle lag, intercooler heat loading and exhaust manifold backpressure.

[@myklesingh8253]

Yeah . maths is involved here

[@BHamon]

I'm still trying to figure out who buys a cold air intake that actually stops in the engine compartment. Isn't that called a short team intake instead of cold air intake. Because cold air intake is going down in front of the tire well Where the factory piping is. Which picks up cold air.

[@briancossey9724]

I've met you and you are always asking me how stuff works

[@james8662]

This question was answered 50yrs ago. Cars from the 60s anyway, many came with cold air intakes.....esp performance cars. The general rule of thumb is cold air makes for a 10% torque gain over hot under hood air. Race cars usually have some cold air setup. A higher cfm filter can help at higher rpms. Usually the web doesn't make people smarter, hence millions of pod style filters sold today. Pod filters usually ruin motorcycle performance also eliminating air box cooler air.

[@randallslonakerii1849]

Yes comes down to computer system and engine. Same as plumbing or HVAC, the more bends or transitions from one size to another greatly affect the airflow and velocity. The cooler the air the denser it is also the more velocity the more air can go in also mix with fuel better. Same as exhaust, run narrow tubes to keep the velocity up for more torque for trucks ( that dont see high rpm) the best would be start off big diameter at filter and slowly get narrower to the throttle body but never go back up in size before throttle body.

[@fettyyyy2825]

it doesn't mean anything, it entirely depends on the stock settup.

I recently bought an K&n intake for my Mazda B2500 pickup truck on eBay for $170 Brand new cost $355 And based on my experience I would have to agree with his statement. It really does depend on the vehicle. For my truck, it does make a significant difference. Nothing crazy, but it does perform a bit better. Especially when I step on the gas on 3rd or 4th gear. It responds a lot better. Gives it a little boost It was a great purchase for $170 I wouldn’t pay $355 Not worth that much money in my opinion.

[@EurekaRecycler]

so you are saying that cold air burns more efficient than hot air?

[@richwilliams9895]

I suppose the best method would be to have less restriction on filter but double skinned pipes and filter housing all metal and made like a thermos flask so the heat from the engine won’t affect the air intake. However this would probably be very pricey and require more space in the engine bay.
