Well my first mod was an Intake. Then I get the JUN. Now I put on the Crawford and hear another noise..

Stillen Intake: Makes a nice loud wisle and psshhttt sound when switching gears.

JUN Flywheel: The first 2 days made a cement mixer type sound. Also after you drive a lil and stop your rpms would drop to about 450 and would start making a very loud noticable clunk noise. So I had Infiniti boost the Idle to 800rmps and all clunking is now gone.. And the cement mixer is definatly on low now..

Crawford: I added it and it makes a ummm hallow type of sound. Cant realy explain but it is noticable but it sounds soooooo koooooool.. It hides the other sounds a tad. But while WOT or just regular it sounds great!!

Soon Ill be putting on an exhaust and have another sound to listen too hehe cant wait.. I love my setup it has done good for the car.. The car feels MUCH faster now and have 1/4's to prove..

I highly recommend the Plenum it is a major diffrence!!!
