Restore factory performance while upgrading durability with the SWAG Performance High-Temp Coated Exhaust Manifold Kit. Designed specifically for Ford's 3.5L EcoBoost engine, this complete kit includes both left and right exhaust manifolds along with the necessary installation gaskets for a hassle-free repair.
Unlike standard bare cast iron manifolds, the SWAG Performance version is finished with a premium matte black high-temperature protective coating that helps resist corrosion, reduce surface oxidation, and maintain a clean appearance even after repeated heat cycles. The coating provides long-lasting protection from moisture, road salt, and harsh engine bay conditions while delivering a premium OE-style appearance.
Each manifold is manufactured from heavy-duty cast iron with precision-machined sealing surfaces for dependable fitment and leak-free performance. Whether you're replacing cracked manifolds, repairing an exhaust leak, or refreshing a high-mileage EcoBoost, this kit is built to provide reliable, long-lasting service.
