gerg 10,871 Posted December 13, 2014 If they sit higher, they might hit the plenum and/or throttle body, for which there is a runner spacer that adds about 10mm to the height overall. Any other issues i really don't know. Share this post Link to post Share on other sites
Trev Vaa 1,185 Posted December 14, 2014 from memory you need to put a spacer in the plenum to clear the top half of the intake. Share this post Link to post Share on other sites
