Just got my 5/16" spacer installed and , WOW! I can definately feel the stronger pull. Seems like the car just wants to jerk forward at the slightest throttle pressure. No issues with the install and no clearance problems. Also, the sound it puts out is a little deeper than before. The sound that comes out of my HKS exhaust is pure XTC!!

Oh ya, I just got my EVO-R Air Duct in the mail today. It's gonna be a nice weekend for me

 

Right On!

Glad to hear its working so well.

BTW -> Dejavu! I got a PM from Rednezz. He just installed it with the same results.

They seem to work well with a good exhaust system.
