An old argument

[siguaw]

I always argue with the local rice burner guys about their so called "cold air intakes" I was taught by father as a child the colder the air the better. So why do these guys use those cone filters under the hoods? My cousin did this on his EX and it ran like crap. Here is a little evidence incase you guys make the same argument. I'm posting it in here because I believe this is relevant to modding your own EX. Enjoy Just a side note I had a buddy that had one of these stuck out in his wheel well and went through a big puddle. He sucked up a ton of water and filled 1 cylinder and busted the connecting rod.

Since I owned imports & American muscle as well as POS's. It's all about the intake design & the car it goes on.
If the stock intake is restrictive any opening of it will yield a increase even if the filter is in the engine bay.
Combine a CAI with tuning & you will get a very good gain that will yield real street results. My CAI in my SRT8 is sitting in the engine bay. But the design of the intake tube creates a air surge at the TB that forces the air into it. Large end on the filter side smaller end on the TB side. It's proven to give gains, & even more with a tune.

You can not measure an CAI on a turbo car. Their dyno's using a turbo car are meaningless. This has been discussed on many other forums with those specific tests.
A CAI will work well on some cars & not so good on others. Some ECU's will adapt to the increased airflow & pull timing to counteract to get the A/F tables back to their set points. Which is why some cars don't feel any different after a few miles. This is where tuning comes in.
