INTAKE MANIFOLD ASSEMBLY
SKU: D00I 615-801
Moderate — 2–4 hours
Overview
Improvements include a redesigned, square IMRC shaft that is more secure than the factory's cylindrical, screw-in style. Additionally, this manifold features an extra support column at each runner and enhanced shielding to protect the IMRC motor from debris, leading to a more durable and longer-lasting repair. It is constructed from plastic and is street legal.
