This is our top mount manifold for the e30 m20 engine. Manifold can be made in t3, t4, or vband. This manifold fits under hood with no mortifications to the chassis, and can retain AC. It's a very low profile manifold and made with 1.25in Schedule 10 stainless steel. Don't fall for low quality copies on the market, as they simply do not fit as MINT as these do!
