Smooth transitions in the mandrel-bent aluminum tubing decrease turbulence and minimize pressure loss, increasing horsepower and torque. The BladeRunner charge pipe kit provides a smooth transition between the turbo and the engine for lower operating temperatures and increased power. This charge pipe kit includes high-quality, stainless-steel, spring-loaded T-bolt clamps and heavy-duty, 5-ply, polyester reinforced silicone couplings. This pipe kit features factory style billet aluminum quick-connect adaptors with o-ring seals to ensure a leak-free fit while maintaining superior strength and durability. Finished in wrinkle black powder coating with a unique laser-etched aFe power logo for a custom look.
