Big Boss Extrude-Honed & Coated Manifold for Caterpillar C15 ACERT Engines. Extrude Hone Uses Advanced Surface Solutions, to Remove Rough Cast Surfaces that restrict Flow, Efficiency and Horsepoer of Performance Components by Enlarging and Uniformly Polishing Internal Air Passages, the Flow Velocity is Maximized.
Forged from HSM material, PDI’s manifolds eliminate the warping and cracking problems of an OEM manifold. With a high moly content, the worry of center-divider failure and metal dissipation is eliminated. Each manifold is designed with a full-contact joint, which allows for heat and flex at the joints, while holding a tight, efficient seal. Each PDI manifold includes high strength, quality studs for added strength and durability. Improved air flow helps to lower exhaust temperatures, reduce turbo lag, and increase horsepower and torque.
