I put my 350z Intake on today. It took 15 minutes. It looks great and sounds better. I jumped out on the road (not residential) to test it and their are people walking on the sidewalks as I chirp 2nd and 3rd gear. I hope I didn't scare them nor **** them off. I got back in the garage and closed the door. I got the intake off of ebay for 67.00 after shipping and handling. I like it more than the injen intake already and i haven't even put on a K&N filter yet.

 

Wait till you couple it to a Conical filter such as the Stillen or
JWT Pop Charger. It howles bad ***!

Also check the thread regarding the z-tube rubbing on the AC line. Make sure you have enough clearance.
