Custom intake for C280. . .

[dshenberger]

Has anyone tried doing a custom intake by putting a large cone filter behind the bumper and runnning an aluminum pipe up to the MAF? Something like this Dinan for an E46. http://www.e46fanatics.com/howto/howtodetail.php?howto_id=10

i did that b4 with PVC pipes from the hardware store

it works...and it was LOUD!!!!!

but i dunno if it actually does anything besides being loud.....my butt dyno tells me that it didnt make any diff in local stop and go traffic...but it did felt that it made a diff on the freeway

this is what i had b4
at first i was just using some hoses

then i went with PVC pipes and wrapped it around with some insulation (very ghetto)

I considered trying the pvc thing! :) Looks like the filter is inside the wheelwell:D Thanks for the pics.

well not really inside the wheel well...you can see it in that pict was because i removed the backing inside the wheel well and thus you can see through the wheel well into the front of the lower bumper

this is a better pict

so do u do anything to it when driving in the rain?

that's where a 2nd car comes into play for back-up. :)

lolsss nope because water really cant get into it unless you are driving through HUGE deep puddles

and also that long running tube from the bottom all the way up to the engine's intake is quite long so......it really takes a LOT of water to get it all the way up there....

Seem to recall that J Irwan built a custom intake for his C36. Don't know where that post is anymore.

Personally, intakes just seem to make noise. The performance gain is negligible, considering the stock airbox is pretty free-flowing as it is.

I beg to differ :), check my intake post

Are there any downsides to aftermarket intakes?

There are potential problems with some intake systems. Most manufacturers utilize less dense filtration media in their filters. This equates to increased pariculate matter injestion via the intake. This depends on the manufacturer's choice of filter media and is something to be taken into consideration. CAI can be suseptible to water injestion. This is because through their design the filter media is quite low in the fenderwell. Extreme caution should be used when driving through standing water or other areas where water is present. The major downside of intakes are problems with the air/fuel ratio.

Do intakes cause problems with the air/fuel ratio?

Many seem to believe that since their XXX intake does not cause a CEL or exhibit any driveability problems, then their XXX intake must be good. Though the apparent increase in power gives them peace of mind, what they don't take into account is their intake is actually causing unseen harm to their engine. This is generally due to two reasons:
1. The intake piping diameter is incorrect. This can cause a lean condition in the case of larger than stock diameter piping or a rich condition with decreased diameter piping.
2. The air flow is not laminar. The stock piping, through it's apparent unusual design, is constructed to smooth out turbulent air flow. Aftermarket systems do not take this into consideration. When turbulence occurs, the MAF sensor will suddenly see more or less air then it had previously. This will cause the ECU to respond by making the engine run leaner or richer for as long as the error from turbulence occurs.

I've used something similar, mainly for the sound. The second my MAF died, the intake system came out with it. Don't know whether or not it made it go quicker, but keep a second one on hand just in case.
