What about K N drop in ?

 

With a tune of course. I would not have it any other way.

See the part about the modded factory airbox. The K&N Drop in is the reason for the MAF skew but the AEM elbow causes the surging on cold starts and when letting off the throttle.

 

He's the master tuner. Of course it's going to be tuned.... LOL!

 

but what about on a stock airbox w/o the airbox mod.

 

Gotcha. I will add that in there in a minute. I updated the first post with a conclusion and my opinion on an ideal intake setup for the LNF Cobalts.

 

You should also add info about the airbox mod without using that AEM elbow. That would be my 2nd choice as best intake. Snorkel Mod + K&N drop in and stock elbow made 4-5% LTFT (can't remember if it was +/- tho)

 

I am pretty disappointed that cpe never got on the ball for ss parts. I'd love to see them make a intake for our cars, as this was a very similar issue the ms3 had...ugh!! I'll email the main man over there again one more time.

 

It is within 1% of the airbox with the drop in only. Removing the snorkel completely is a bad idea because that snorkel acts as both a velocity stack ( the bell shaped end helps funnel air) and also helps straighten the incoming air some before it hits the filter. Removing the snorkel while running a K&N Drop in filter causes a -7.2 LTFT and -17 to +10 STFTs because of lots of turbulance over the MAF.

 

So, when should we expect the "Terminator" intake?

 

If I had the tools and materials to make it I would.

 

Nice write up. this and the downpipe thread need to be merged! and removed of all posts and locked.

 

Thanks. I ended up accidently creating 3 of these threads because this site is so slow it never loaded the page and I kept clicking on the submit thread button. I got rid of the other threads. This one has some updated info in it as well.

 

You could construct it one molecule at a time and have it out before K&N.

 

So basically you're saying the Hahn is the best?

 

and CIA does nothing ? ^

 

So far it is definately the best overall.

 

I don't even think I want to bother with an intake, seems like too much trouble lol.

 

The couplers need to be resized (cut down) and reinforced because they crush, kink and collapse easily.

Tuning this car for an intake is difficult to say the least but there are large gains to be had especially in top end power compared to the stock airbox.

 

I'll see if my boy wants to bother with that lol.

 

other then the couplers, are there proven tuned gains from it though?

 

I have never seen a third party dyno sheet or any other dyno sheet showing the gains with either of CIAs intakes so I am not sure. Normally if you are tuned and you add an intake (tuned for of course) there is a noticable difference in acceleration shown by my data logs. I can feel the difference in my car especially at 24 psi and the logs show a difference in both airflow up top and shorter hwy acceleration times.

 

What size are most of the intake pipes? 2.5'' or 3''

 

well thats what i was wondering thats term . . when i get the intake ( cai ) and my logs ill gladly post them, i just got off the phone with dan, hes starting the bends on the 3 inch with new couplers

 

Well AEM is gonna take my car again next week

 

with a tune for it ya damn we are so f'd for stock use I think :/
