Just a quick question for those of you who run a cold air intake or one like posted in the pic. Do you remove the factory air filters under the engine cover or run both. It seems that it would be restrictive and redundant to run both. I realize the system pictured is not a true CAI but it does show it connected to the factory cover.

What is pictured is a HAI ( Hot Air Intake ).
If you run a true 3" CAI, there is no room for the OEM cover.

or

The choice is to use an old C320 cover, or none at all.
see needswings Mercedes V6 Engine Cover for the cover picture.
( Rob's a bit high on that price, I got mine off fleabay for $40 shipped )

 

To answer your question.. Remove the OEM filters and seal the boxes back.. whether a foam rubber gasket type or silicon.. your choice of method.

 

Yes, I suppose that would be the proper answer.
I got carried away, my apologies.

 

Thanks for the replies guys. No need to apologies ala_xfire, I am running the stock setup but I was just curious what was done with the stock filters.

 

Which MB did this cover come from? I need to find one on EBAY.

I prefer this on off E-Bay as the other one has a cut-out on the right which looks strange as it has no purpose on the Crossfire.

Agreed, it looks much better, but I thought your question was concerning an engine cover you could use with a CAI installed.
That dog ain't gonna hunt.
It would be fine if you are installing a HAI like mrmiata did.

 

28 degrees.. so explain to me how much hot air is getting in now! LOL


And as a note... have you actually looked at temps and HP gains on intakes..?


"The rule of thumb with the average V-8 is 1 hp for every 10 degree (F) drop in intake air temp. That works out to about 1% for 30 degrees."

 

As a matter of fact, I did, and concluded that CAI's ( including the DCAI ) are a total waste of money for a N/A engine.
Unfortunately, I did this after I installed my CAI, but hey, I only paid the guy in San Diego $100 for it, and it looks cool, so it stays.
People at car shows comment a lot about the raised "Needswings" on it.

 

I'd take one at 100 bucks myself.. LOL I think the "less restriction" is more an advantage over temp gains. And as you say.. they do look cool... LOL

 

from what I understand, cold air only helps NA. More air helps boosted cars. More cold air should help both a bit as well. As for how significant the gains are??? only a dyno will tell.

 

Pretty much true, as the air is gonna be hot with a supercharger or turbocharger anyway, so the temperature of the supply air is of little factor.
However, all I have read points to little overall gain on a NA engine.

 

WRONG engine cover. That one is for a V8. Here's the correct one...

50% larger air filters allow much more air flow volume. More than enough for the upgraded 74mm TB and 3" MAF.

 

And feeding from the OEM radiator openings your still restricted down to what maybe 2" per side or so.

 

I would disagree about that. Either NA or supercharged will benefit from a reduction in intake temps. Lower temps equal more dense air, equals more power. I can not tell you how much gain for each drop of 10 degrees, maybe Rob can. This is governed by the laws of physics but applies to all internal combustion engines.

 

Point taken, maybe I should rephrase :

There is little overall gain from a N/A CAI for the amount of money spent.

 

This assumption goes against all the testing done. Granted, the standard crossfire set up is actually a cold air set up. The needswings set up opens up the flow with larger intake tubes but draws the air from the same place the original set up does, just with larger opening and filter flow designs that are less restrictive as well. More air flow, equals more air and the fact it's stilling being drawn from outside the engine compartment alledgedly increases horsepower potential. Drawing in winter temp air certainly helps a great deal too -- because it's more dense. People can dispute the gain / gain potential, but it's more than just asthetics, especially with a tune. I haven't dynoed mine but the DCAI and the tune certainly have had a real seat of the pants effect on the car. Additionally, the testing people have done, including EC and Needswings seems to support their number gains.

 

Alright already, I'll shut up.
I installed upgrades in this order :
1. Needswings single CAI - no appreciable difference although my UltraGuage said it dropped the ambient/IAT difference by about 10 degrees average
2. 74 MM throttle body - again, no appreciable difference
3. EuroCharge tune - BIG difference

These results evaluated with only the ole butt dynomometer and timing 0-60 and 1/4 mile on a country road
