Stage 2 Manifold Porting (BK1 3.8)
Core exchange available – requires core deposit.
Please note these are scheduled and are not shipped immediately.
Our Stage 2 BK1 3.8 manifolds offer the same mid-range torque as the stage 1, but improves the top end by eliminating the oddly shaped and narrow mouths of the runners. We cut the manifold in half so we have direct access to the ports to get them to the perfect shape, letting your 3.8 breath until redline!
