Dress up your engine bay with our M90 vacuum port block off plate. We designed this plate specifically with Fiero 3800 swapped cars in mind to increase hood clearance and to offer a clean look. 

We do not recommend this plate for W-Body cars running the factory vacuum system. 

CNC block off plate includes low profile socket head bolts along with sealing o-ring. Available in anodized black or clear finish. Fits Gen 3 and Gen 5 M90 superchargers.
