Sorry Greg for some reason I don't always get my notifications. I got the Stack Racing Intake Spacer ($40). I honestly can't tell what the spacer does because I put the new EGR on same time & replaced the BBK underdrive pulleys with Steeda. So It runs alot better just can't pinpoint exactly what difference each part makes seperately
An aftermarket upper plenum and 70mm or 75mm throttle body will make a very noticable difference in power and response. Full 2.5 inch exaust makes a big difference too. I really like your car. Keep up the good work!!
