I'm wondering which one I should choose to put in my 06' S40 2.4i? A panel filter or a cold air intake system? Thanks for the help.

 

That all depends...

1. What is your budget?

2. Do you want to stay basically stock and or mod your car? Panel filter (Even if a K&N is still basically stock, IMO) / CAI is modded.

*FYI, the CAI that is available isn't cheap. Something like $250 I think. Unless you create your own CAI.

 

Imo, cai!

 

gotta go with the cold air man. unless you are in an area with lots and lots of rain and stuff. then just be carfull where you are putting the CAI filter (not to low to the ground)
