LS1, LS6 & LS2 Intakes

Mast Cathedral Port intake manifolds are designed for maximum performance without compromise.  We were the FIRST to cast our intake in two halves to allow the manifold to be completely CNC machined.

If you want all out performance for your LS1, LS2 or LS6 engine look no further than Mast's line of cathedral port single plane intake manifolds.
