Mercedes C400 BMS Cold Air Intake Kit Install

[@JuiceBoxKev510]

Sick bro... I have a c450 that I bout 2 weeks ago, just took it to MB for a full service and guess what came in the mail today... Cold Air Kit and Burgers Blow-Off Valves... I'm already impressed with how yours sounds... Can't wait to hook this all up tomorrow!

[@MercedesMan]

How are your blow off valves? Same engine here in my e400 i was hoping a blowoff would sound good on this engine because the stock one is so quiet

[@thtc400]

Id love to see some more about the intake, i have a c400 as well and am contemplating doing the JB4 tune + intake combo.

[@DavesMotorCars]

What would you like to know? I want to do a JB4 but i have a warranty and done want any issues down the road.

[@chin6822]

@@DavesMotorCars does adding the intake void the warranty? I have a c450

[@DavesMotorCars]

@@chin6822 Depends on your dealer maybe but I've had warranty work done no issues. nothing engine related though

[@jacobphinney4711]

I know its been 4 years, not even sure if these are still installed. Ive had my 400 for about a year now, and was thinking about doing this. I know the question was asked already, but after having them on for some time, how is the heat soak? I know the M276 engines run hot

[@DavesMotorCars]

I’m not sure I dont own this car anymore, sorry!

[@iLazarus_xD]

Thanks for the video!

[@kylearmour888]

Hey quick question for you, What are your thoughts on this intake system? Is heat from engine really a concern? Would you recommend this system for c43 owners? Appreciate you, thanks for the great video.

[@DavesMotorCars]

i wouldn't worry about the heat, it doesn't seem to make that much of difference, it comes with heat shields and i think they a pretty good job. would be great for a c43 the difference is definitely noticeable!

[@kylearmour888]

Thanks bro I got them installed too haha

[@ergjusk3720]

Do you know if something like this voids the warranty? And have you run into any problems since its been a year?

[@mikedennis8213]

Looks good bro! Time for jb4

[@hg1496]

Hey Dave, any performance benefits? throttle response? quicker?

[@DavesMotorCars]

Feels like there is for sure.

[@StevenTorres53]

Is the dual intake your using carb compliant? Will it pass smog? I’m interested in the same one for my c43.

[@DavesMotorCars]

I never worry about any of that lol

[@dronesmontilla8435]

Hello guys, how are you? I have a Mercedez Benz C 400 2025 with 75,000 K and it is giving me problems, the engine is consuming oil in 3 months I consumed 1/4 of the oil I went to the dealer and they charge a lot just for doing a check that they recommend.

[@DavesMotorCars]

Thats crazy lol sounds like a bmw, i never had any issues like that.

[@fabioborguezan]

And what about heat protection? These air filters are like inside the engine.

[@DavesMotorCars]

There is a part in the video where i installed the supplied heat shields

[@WaRy740]

Do you still have the factory exhaust on it? It sounded like you have an exhaust! Lol

[@DavesMotorCars]

Still factory exhaust, hoping to change that soon

[@308rell]

the cls400 has the same engine right ? i’m a able to use the same parts you have on yours on my cls400?

[@DavesMotorCars]

not sure if it's exactly the same or not

[@Quesor7]

The heat shields were a bitch to put on but got em on haha

[@randomstuff7277]

Do you have aftermarket blow off valves or just the intakes?

[@DavesMotorCars]

just intakes that's it

[@arlokkkk]

Is this called cold air intake? It looks like a short ram intake. Cold air intakes usually goes down behind the front bumper.

[@DavesMotorCars]

It's just a general term used when the stock airbus is removed. This particular car does have airducts that directs the air towards the intakes.

[@ritseee]

Do you have aftermarket blowoff valve too?

[@DavesMotorCars]

nope that's just what the CAI does

[@anthonysanchez1361]

Can you run the intake without a tune?

[@DavesMotorCars]

Yes, i have had zero issues.

[@ahemgee9542]

Not much benefit if doing this unless the car is tuned as and running higher boost. Also you need to dyno it and or run some Dragy times to measure the before and after improvement.

[@DavesMotorCars]

Not true, all modern cars can self tune the AFR for slight modifications. Anything more than this though and you'd be correct. I don't plan on doing any other mods at this time.

[@terrencehewston7248]

Does the engine cover fit back on

[@DavesMotorCars]

It does not unless you modify it

[@ygtkrmn]

Where we are going to face the sensors?

[@DavesMotorCars]

what?

[@ygtkrmn]

@@DavesMotorCars the sensors on the intake not the oem ones bur the ones that comes with the bms dual intake which way should we face them after we hook up everything?

[@ygtkrmn]

4:58 on your video that shows the sensors

[@DavesMotorCars]

@@ygtkrmn they are oem sensors with an extension connector

[@ygtkrmn]

Ok thanks

[@azrzu3085]

Does it have more hp?

[@DavesMotorCars]

Theoretically yes, usually 5-10hp gain

[@NotAlone.43]

Any complications?

[@DavesMotorCars]

none as of yet

[@NotAlone.43]

How about now ?

[@tsnaha]

Buy some finger nail clippers

[@DavesMotorCars]

lmao i have some thanks

[@jagplaha9959]

Lets spend more money we didn't need to, let's do a bunch of mod work cuz we bored, only to suck in engine heat from 360* and make less power! But it "sounds" good...

[@DavesMotorCars]

guess you missed the part where the heat shields were installed. The oem vents provide direct cool air from outside.

[@jagplaha9959]

@@DavesMotorCars - I'm sorry my friend. It's a nice attempt, but it's not gonna be better than the stock airbox and air intake that they spend thousands and thousands and thousands of dollars researching and building. A real cold-air intake will be 100% blocked off from the engine compartment

[@DavesMotorCars]

Thousands of dollars worth of research to make it EPA approved, has nothing to do with performance. Aftermarket will always be better.

[@DavesMotorCars]

Stock paper filters and air boxes suffocate your car, thats a fact.

[@jagplaha9959]

@@DavesMotorCars - yes true Dave. I have been running a proper aftermarket cold-air intake with a K&N filter on my Genesis 5.0L V8. The filter is sealed off from the engine bay entirely, it's only source of air will be 100% fresh air from outside. I am now looking for a "proper" cold-air intake for my CLS 550...which is why I came across your video...
