Flow and Performance: Smooth transitions in the mandrel-bent aluminum tubing decrease turbulence and minimize pressure loss, increasing horsepower and torque. Wrinkle Black Powder-Coated Finish: Not only does the black powder-coated finish make for a striking look, but it also insulates the tube from engine heat and protects from corrosion. Perfect Fit: These tubes include high-quality stainless-steel spring-loaded T-bolt clamps and heavy-duty five ply polyester reinforced silicone couplings. This intercooler tube kit features factory style billet aluminum quick-connect adapters with O-ring seals to ensure a leak-free fit while maintaining superior strength and durability.
