Smooth transitions in the mandrel-bent aluminum pipes decrease turbulence and minimize pressure loss, increasing horsepower and torque. This charge pipe kit provides a smooth transition between the turbo and the engine for lower operating temperatures and increased power. This kit includes high-quality, stainless-steel, spring-loaded T-bolt clamps and heavy-duty, 5-ply, polyester reinforced silicone couplings for superior strength and durability. Finished in wrinkle black powder coating with a unique laser-etched aFe POWER logo for a custom look.
