I have a CHP Plenum spacer that I have been planning on putting on my car for a while because I was not going to change the plenum or throttle body because I am planning on getting a Kenne Bell in the future. I ended up getting a really good deal on an Accufab 75MM Plenum and throttle body and now I am trying to figure out if I should put the spacer on when I put the new plenum on or not. Has anyone seen any real gains on an NA car with a plenum spacer?
