CAI is a simple bolt on that I'm getting into soon. What CAI kit have you guys found to be the best as far as power gains? Also, which one was easiest to install?
K&N FIPK, JLT, and Steeda all make good CAI's that perform very well. Each has it's pro's & con's but most people go with either the K&N or the JLT as far as the 03/04 Cobra is concerned.
If you do a search you'll find we've discussed this very subject many times in the past.
I have a Steeda which works great. I would have probably gone with a K&N but I bought the car used and it had a Steeda already on it. I can't complain it looks really good and seems to do the job.
