I did end up wrapping it in aluminum tape to protect from heat near the engine but I never had an issue with it. It was a ton of fun. It had a 1.5L and 5sp. I did a whole lot of porting and old school hot rodder tricks and before it blew up on the bottom end I got it on a dyno. It made a whopping 118 whp. Much better than the stock 80hp.

Isn't most OEM intake piping abs plastic? People here have been using PVC piping as intakes and I've never seen them melt or anything from the abuse.

[@NothingXemnas]

@@Flako92 Yes and no. PVC is naturally very hard, brittle and hard to mold, so they normally have substances called "plastifiers" to make them, well, plastic. Different proportions of different plastifiers can make two objects made of the same base polymer have completely different characteristics. That said, if they could, they should go for pipes made for hot water, which can withstand temps near boiling point.

[@crash4x3]

Because of how thermodynamics work (heat transfer) it is entirely fine to use this in this application. While the surrounding temperature might exceed the temperature rating of the ABS pipe. The cold air moving through it at a high rate of speed will cool it down faster than the heat from the nearby motor will heat it up. It comes down to the efficiency of heat transfer of convection heat transfer (the heat coming off of the engine) vs the efficiency of advection (the heat transfer from the pipe to the air moving through it) advection transfers heat energy at a much higher rate than convection. It the same reason why air fryers work faster than convection ovens. It's the constant movement of air.

But what about when the car is parked after a hot ride, engine compartment soaking in its heat? Would you need a turbo-timer also hooked up to a fan, just to cool down the engine compartment, before shutting off, just to protect PVC?

If you're going to do this for your engine what you want to do is coat the outside in a high temperature insulation, one with an aluminized surface would be best to reflect the heat away from the pipe. The problem with plastics like this is they'll heatsoak pretty easy and ruin your power gains from any cool air, but if you insulate the pipe it can stay cooler as the air travels through it and keeps it somewhat cool, and your IAT cool too.

[@GeekOfAllness]

I've melted ABS when I hooked it straight up to the turbo inlet, but a silicone coupler to give it a couple inches worked fine for low (7 psi) boost. As long as the pipe isn't touching the manifold or radiator, I don't think it would be a problem. I still tend to just get the AutoZone pipes that are lighter for a bit more money. I've never spent more than $100 doing an AutoZone intake.

Home Depot is cool! I made driving lights from stuff from there and got different colored bulbs and made a fart can exhaust tip from their parts! I didn’t have a lot of money but I had some creativity! This was on an 1990 Acura Integra GS I owned years ago. For the driving lights I used exterior garage light lamp holders and 55 watt sealed beam halogen display lamps. They fit right in the holders and I fashioned brackets to hold the halogen lamps out of coat hanger. Some guys walking by saw them and thought they were PIAA driving lights! Cost me like $20 total back then. In the lawn department for accent lights there are 194 style push bulbs that are different colors. I used the blue ones because I thought they were pretty but unfortunately a few days later I got pulled over by a state trooper because he said blue lights are supposed to only be on police cars in Massachusetts. Oh well… I couldn’t afford a fancy exhaust system so I used to cut off inlet and outlet pipes from rusted exhaust systems as I worked at Acura and used different mufflers like a turbo muffler or a glass pack muffler to try a different exhaust sound but I didn’t have a good exhaust tip. So I decided on using a Home Depot toilet collector pipe that was 4 inches wide that looked perfect. To test to see if the PVC would melt I strapped a piece of scrap PVC on my exhaust system and with the driving I did around Boston it did not melt. But more on that later. I used a couple sections of pipe to funnel it down to fit my exhaust system and then I drilled a hole in the angled part of the toilet collector pipe and put in a amber lightbulb so at night inside the exhaust tip would glow orange likes it’s on fire. Spray painted it chrome. The looks of the people’s faces in my rearview mirror was priceless! Unfortunately on a 2+ hour drive to Maine the tip started to sag so I removed it. Was cool while it lasted. Oh, and when my Honda Odyssey needed a motor mount, head to the chain department!

[@bleachstain9785]

When you extended the pipe, you lowered the tuning frequency of the intake to a point that’s beyond your hearing capacity. You can use a mathematical equation to tune your intake, using the internal volume of the intake manifold itself, as well as the internal area of the piping, you can lengthen or shorten it as needed to get the right frequency. Similar acoustic mechanics are used when designing a ported subwoofer box or ported loudspeaker enclosure.

We used 3 inch PVC pipe to re-locate the MAF and cone air filter out of the engine bay. The MAF and air filter now sit in front of the radiator. PVC was used to run from the old MAF location at the air manifold intake, down behind the radiator fan, around the passenger side of the radiator, and in front of the radiator. We've also added a "box" around the back of the filter to direct more cold air into the filter.

[@chadg6874]

This idea sounds pretty genius! I was just thinking, couldn't you have one line of cold air coming from the PVC pipe and still keep the factory air box to add even more

[@chadg6874]

Have you had any issues with water ingestion?

[@Antykain]

I built a similar intake for my old '01 Subaru Outback after the stock intake piping started coming apart. Built it about 5 years ago and it's still on the Outback today. I routed the intake piping into the passenger side fender above the wheel well, so it's not pulling any air from the engine bay at all. Those '01 Outback didn't use a MAF sensor back then, so.. no worries with that.

[@krazyk86cu]

Lol, you can see it in Zach's eyes, he didn't wanna ruin that nice TRD intake 😂

[@formdoggie5]

If you got rid of the bend, it would've probably added power. Bends decrease the relative air velocity, which decreases total intake capacity, even with same diameter housings.

[@RCTrend]

Yeah, that k factor tho. That elbow has me cringing

[@FreebornOutdoors]

Agreed I do HVAC and it’s the same with furnace exhaust pipes a swooping 90 instead of a hard 90 would also increase airflow a bit

I made a pvc intake like that a year ago for my buddy's 2003 nissan maxima. It sounds amazing and improved mid the high rpm power.

[@2000impalalsx]

I did this once in high school...used 90 degree adjustable duct tubing (where you spin it around and make anywhere from 0-90 degree) sealed it up with aluminum duct tape and covered it with underbody spray (the spray can). worked very well. Though I would throw a code any time the outside air temp was under freezeing temps (code was P0128) Summer time it ran a bit hot in traffic. but cooled down within seconds once I got moving above 20mph

[@ndtmaster]

Same here. Those were the days. I had a CRX SI.

[@averyalexander2303]

I have used PVC cold air intakes for years with no signs of degradation and no problems at all. I think if the engine compartment gets hot enough to melt PVC or ABS pipe, the intake is probably going to be the least of your concerns.

I made an intake for my old Grand Prix because the previous owner had left the stock air box, but just stuck a pod filter directly onto the throttlebody, and it looked like crap. I made a heat shield box out of sheet metal meant for patching HVAC ducting, lined it with aluminized bubble wrap stuff as well. Version 1 used some universal flexibility intake tubing i bought online, and I just used a 4" PVC connector to attach the filter to the tube. For Gen 2 I upgraded to the lager throttlebody from a Northstar V8. Got it, the external MAF, as well as the factory intake tube from the junk yard Cadilac for like $60 iirc. Throttle body -> intake tube -> MAF, stuck one side of the MAF through the hole in the heat shield, and attached the pod filter directly to the MAF. It actually ended up looking pretty professional, and still a fraction of what any aftermarket intake would have cost

[@keithmccormick5496]

In my younger days a ran one of these in a 94 civic for several years. Picked up a couple mpg and loved the sound. No issues with it melting. Just don't let it sit on the radiator and you'll be fine.

I had a 1993 Cavalier Z24 and I did this exact intake on it. Same Autozone filter. It made the 3.1 sound much better. It actually gave a noticeable power increase as well. I was quite surprised with it.

[@erichindman1132]

I made a very homemade turbo kit for my 2002 Subaru 2.5RS with a bunch of random parts back in college, but forgot about the charge pipe. It was 6pm on a Sunday and had to drive and hour back to my college town to be at class on Monday. I used PVC pipe from the hardware store for charge pipe. I was only running 6psi so it worked really well. I was going to fix it but people kept wanting to see it and I wondered how long it would last. Was on the car for over two years as and held up great.

[@AriaESDF]

With some paint i dont think most people would notice it’s a DIY and i doubt it makes a huge difference in power positively or negatively so hey if you like how this sounds and don’t wanna spend $300+ on a CAI then maybe go for it :)

Question- what about turbocharged cars. Because they can be finicky without a tune?

Depends on the car, and if they use a maf or map sensor. My turbo car uses a map sensor, and an aftermarket intake did not cause any issues.

I feel like you needed to talk about the downsides to this. The reason intakes are so much money is because they can guarantee nothing goes into the engine that shouldn't be there. Because along with it melting, you could be letting dirt into your engine (the entre point of a intake/ air filter)

I did the poop-pipe intake for an ls1 about 15 years ago. Great noise but probably negative power outcome. The thing started warping within a few days but it was still usable for a long time, probably a few months before I replaced it with a purpose built one. Also, where I am at least (NSW, Australia) it's illegal to have a pod-filter exposed in the engine bay.

tbh i did a diy intake for me e34 using pcv pipes, the filter box has a cone shaped pipe which bugged the hell out of me, I cut it, cleaned the ut and installed a little bigger PVC pipe which is the same length using epoxy. i cleaned everything up using those small "grinders" then painted the whole thing heat resistant black (used for room heaters) and installed it. till now almost everyone who looked at my engine bay thought it was factory like that. i never been happier

[@HarleySLA]

Not an engineer here, I don't know that the home made pipe would ever melt honestly. It does get pretty hot in an engine bay, but where that is mounted I feel like the fan would direct air towards it to cool the outside. Not to mention the air flow inside cooling the inside. The only issue I could see arising is it (plumber) cracking over time. Honestly though this isn't even much of a negative because most intake pipes will do this (see video of Jobe working on the E36 where he says he'll have to tape where theres a hole in the factory (im guessing) pipe). Super common to see on the cars I work on: Hondas, even to the point of them separating completely because the crack went all the way around. Honestly I love this concept, its ridiculous which I'm a huge fan of, but also if youre bored one weekend make one for your high mileage car and keep it around in case yours fails because unless its metal it will definitely fatigue and crack and/or break. Props guys, if you weren't several thousand miles away I would love to volunteer to come do ridiculous shit like this one time, I wouldn't even want compensation, the sheer ridiculous nature of it would be payment enough.
