M272 CAI: Graphic images, viewer beware :P

[NegroC230]

First off, this is going extreme intake, not K&N insert and i am afraid to touch anything else because its a Mercedes and its expensive!!!! This attempt is made with years of experience in this field. Parts altered are cheap to obtain used and replace in case you need them too. Again this isnt a sissy mod, beginners beware lol! Well, after 2 hours of measuring, cutting, fabrication, bending and fitting , the so called " nothing better then Mercedes ,ram air, design" intake is born. At the present time, im doing final touches and photos. Give me few minutes here. FIRST TEST DRIVE: I believe quite noticeable amount of power was gained. Not to mention engine , feels like is soo much smoother.. Beautiful V8 mercedes growl after 3500rpms. Advantages: - weight reduction- lighter than stock OE intake parts. - temperature control - not only intake inhales cold air , but because the stock intake was removed , now the air that is being forced through the "ram-air" left over ducts if flowing around engine bay and most importantly INTAKE MANIFOLD , which isnt covered up anymore! Disadvantages ( so far): - sound - because the filter is located in the same bay that the fresh air is being sucked into the cabin, you will have sound of your engine sucking in air heard from that area in the passenger compartment. Its sort of like the engine sound tube design, but you hear it LIVE, LOL...... - cutting - some cutting is involved to run the pipe into the neighboring bay. While i was fitting it my way, i took a little detour in my work and tried to see if ram-air could be utilized in another variant of the intake. and the answer is YES, but more brackets must be fabricated to attach it to the valve cover bolts, the other problem is , nobody on the market makes a shielded cone filter ( like K&N makes Apollo ) with a 4" inlet. Our throttle body is 3.5" so it is useless to step down to 3" ( btw Apollo is 2.75" inlet ) - battery - smaller battery required. Which also helps you to knock off another 45lbs Disregard the blue hose and filter, i didnt have any black hoses lying around, tomorrow, it will be fixed IMG_2265.JPG IMG_2266.JPG IMG_2267.JPG IMG_2269.JPG IMG_2270.JPG

where'd you get the materials?

[advans]

lol where in NYC are u from? I need to hear this to see if this is legit.

[NegroC230]

Queens...Maspeth area

[howardyudoing]

well that's one question answered. lol

[NegroC230]

Material was ordered from internet from various stores. Before any job is performed, you take a look at it what you need, measure it , and then you shop around

[howardyudoing]

you have a 4" pipe bender? crazy!

[omg its nate]

Hmm I think I will keep mine stock.

[mleskovar]

So you now have no cabin air filtration, excess unburned vaporized fuel and any battery gasses entering the cabin, cabin air/climate being sucked into the engine, and a sub standard battery. What are you thinking?

[NegroC230]

yeah, that paper filter really helps im thinking i am faster then you , LOL

[Patrick LowKey]

he's thinking mods. lol! good job on the ram air. but i dont think you'll be getting much cold air for your intake at that spot. also like mleskovar said no more cabin filter.. you'll get dizzy allot when the a/c is on.. cheers! still a good looking DIY!

EDIT: bro just thouht about it. make a strait pipe going to the right headlight! lol! remove the headlight and make a housing there for the pipe! now thats cold and fresh! hehe!

That paper filter in the first place, isnt even charcoal, so it really doesnt do anything except for filtering dust. Secondly, this battery is SEALED, unlike the OE unit where its actually vented, and YOU , my friend are inhaling it! Thirdly what fuel are you talking about????

why are you thinking i am not getting cold air at this spot??? if you look closely at the hood, that part of the hood is OPEN via duct on the hood

[Patrick LowKey]

yeah at the top.. at the same time theres still not too many air coming from there.. those fins serve as an escape for the heat coming from the engine compartment.. not going into the compartment.. well.. looks good man. by the way no ones attacking you here so take a chill pill.. lol.

[NegroC230]

OFF -TOPIC here a little...just did a quick research and, i founf out that we have a charcoal filter in the cabin area right next to the heater, which means this air filter in the engine bay is solely for dust ....

i dont feel being attacked, just explaining my idea everybody is in title to debate

[Patrick LowKey]

k k.. by the way what size is that battery??? i really wanna switch mine to optima's but people say it cant be done..

[NegroC230]

everything can be done this is very small and powerful battery ( not reserve time wise, but cranking ) its about 11lbs 8"x3"x9" ? 280cca 300ca very reliable, i had it for 2 years in my E46 M3

[Patrick LowKey]

280cca? that tiny??? what the? serious?

well if any of you guys read my other thread, which i got flamed for...lol. there is a giant space under the passenger side headlight where you could route that fat 4 inch pipe down into. its filled with cold air. try it. after you drive your car, pop the hood, remove the passenger side intake pipe and stick your hand through the fat opening down under the headlight. hella space for any cone filter.

someone also said that it would get dirty... isn't that the purpose of a filter? even if you look at the underside of the front bumper, it's pretty much covered all the way with panels. so i doubt it'll get any dirtier than our current filters.

[mleskovar]

Are you sure you have the charcoal cabin filter in your model? I don't think so. The unburned fuel I'm referring to is what is left over when you back off the gas following WOT and low rpm WOT. Those are worse cases, but it's always there and you don't want to be breathing it. How do you think the throttle body gets all mucked up? As well you are drawing air from a place that is hotter and more restricted than the normal high front facing intakes. Also, that piece that you hacked out is part of the unibody construction and has structural significance. If you do a lot of short hop driving that battery, along with your alternator, will crap out quickly. People on this forum have done extensive testing....read that dyno.....and no intakes or filters have surpassed the stock ones for power. None. One person even tested with NO air filter and the hood open for maximum intake and found no increase. It may look better to you but it's neither safe nor more efficient.

V8 growl from your M272?
Nonetheless, kudos for tinkering. One never knows for certain until he’s proven it himself.

Not sure if that battery will crank it up after a hiatus during a Queens' winter.
Put a real one in the boot to help improve weight distribution.

Is that a Heat Sink ontop of the m272?

To the OP: Only one way to prove your mod's worth. Dyno. (with the hood down) Post smore info about the battery too

Mig has done it. Its possible, I think he used a red top.

[Karo]

I don't get it. I have heard of intakes and know about them but, isn't our original design better? How can it get any colder? Sucks air from the grill as opposed to sucking air by the battery box?

The only plus I see is that it is shorter. Other than that I feel our stock intake is fine and may even perform better.

One thing I learned is on the w203 intake and exhaust hardly do anything. What is the max power you gained 2hp? If you even gained anything.

Can anyone chime in? You guys really believe there will be any gains? I'm not trying to argue or anything I just want an honest answer.

Good job, you should get points for doing it, but if you gain more power than

heat sink indeed. it's the ECU sitting on top of the engine.

mig took his out after his aftermarket head unit drain it.. I still have mine. it's uptima red top.
