Hey Everybody,

New member of ClubLexus here. I got a 2004 IS300, stock. I'm ready to start modifying my car but wanted some suggestions since someone in my crew said AEM is no good. Which cold air intake would you suggest?

 

I went with the KNN FIPK. You can get them for $200-300 depending where you go. Everyone seemed to agree that SRT was the best, but I had a bad experience with them and will never use them again.

Welcome to CL, btw...

 

There is only 1 CAI made for the IS300, and it's made by LMS. All the rest is a Short Ram intake.

FYI: You have to make a hole in your engine bay for the intake pipe to go down. BUT~ you can use the same hole for intercooler piping later on.
