I was thinking of getting a 25mm manifold insulator and a 12mm plenum spacer but I don’t think they will both fit under my strut brace. Your thoughts? Jason July 19, 2023 02:37 Updated Generally speaking, you're only able to raise the ecotec plenum by around 25mm if you're running a strut brace. Best to take a couple of measurements to make sure though. Comments 0 comments Please sign in to leave a comment.
