The SPE Motorsport Passenger Side Exhaust Manifold for 2015-2019 6.7L Powerstroke is an upgraded ductile iron replacement that addresses every weakness of the failure-prone factory grey iron manifold. Snyder Performance Engineering designed this manifold with 30% thicker mounting flanges, a reinforced 30% thicker up-pipe flange, an upgraded EGR flange that uses M8 bolts (instead of factory M6 — which break far too often), and a thicker wall casting that resists cracking and warping from extreme heat cycles.
Built from durable ductile iron (offering greater strength and flexibility than factory grey iron), this manifold retains all factory heat shield mounting points for seamless integration. A precision-engineered direct-fit replacement that delivers long-term reliability where the factory part fails. Designed in-house and manufactured to outlast the OEM unit by significant margin.
Features:
30% thicker head mounting flanges for stronger leak-free seal
30% thicker up-pipe flange for high-pressure reliability
