I've made a CAI for this car, but its factory circ, which is 2", would bumping up to 3" help at all? Keep in mind that there's no BBTB or anything like that, all stock......with a lil throttle in a bottle

 

CAI have lost horsepower at 3"

i would say 2.5" would be best

 

I have a 99 Accent & when I made my CAI...I went from 2.5 to 3 inches (where the filter connects).
I tried using 2.5 all the way & my car wasn't getting enough air. So I went from 2.5 to 3.
That was my experience anyhow. Peace...

 

on an accent?

hmmm
tibbies lost power on a dyno with a bigger pipe... so i dunno

your choice man
i say go with 2.5

 

The Tib does not require as many 90 degree bends as the Accent. I had to use 2 and I had to go under the battery plate, instead of in the fender (as in the RS). That's the main reanson why I had to go from 3 inches to 2.5 inches...to get more air up through those 90 degree bends.

Did that make sense? eek!

 

that does

 

my intak is with 3" pipe and i had no power loss...at least i didnt notice any

 

Big Al your ride is tight.
