THNX! Will Do.

Yes, It is a cone K&N in the engine bay. I just bought the car in april so what intake would you suggest. THNX! <_<

Thnx! It does sound complicated but I get it. B)

Can anyone tell me what double clutching means. No one in Michigan seams to know. thnx!

I would say the SRT Intake is the best for the IS300, it comes with an ecu and there dyno charts say it adds 22hp which is double of any other intake for that car.

Thanks everyone for all the help! The reason I went to the dealer is because the check engine light went on and they said it was a bad air sensor. That is when they told me my car was running lean at wot. They said I had to take my K&N intake off before they would work on it so now i'm going to take it back in tomorrow to get it fixed and i'll find out more, I'll let you know what they said because it sounds like you know more than they do. Thanks again for your help!

What does it mean when my car is running to lean? The dealer says i'm at 45% at full throttle and I should be at 5% could someone explain and could you tell me how to fix it? THANKS in advance!
