This BladeRunner intercooler tube kit delivers more flow and is more robust to handle higher horsepower and boost than the factory intercooler tubes on the 2017-2019 GM L5P diesel. TIG-welded and designed from aircraft-grade, mandrel bent aluminum tubing, the BladeRunner I/C tube kit features factory mounting locations, quality hardware and 5-ply silicone couplings for a secure, hassle free installation.Flow and Performance: Constructed from 3" and 3 1/2" aluminum tubing, both I/C tubes are mandrel bent and powder coated for maximum flow and performance. Smooth transition bends decrease turbulence and minimize pressure loss, increasing horsepower, torque and lowering EGT's. The BladeRunner I/C tube kit transfers hot air smoothly to the intercooler to accelerate heat transfer then cooled air to the engine to help make more power.Perfect Fit: Factory mounting locations, quality stainless steel spring-loaded T-Bolt clamps and heavy-duty 5-ply polyester reinforced silicone couplings ensure a secure install. The cold side tube includes a factory-style quick connect with an O-ring seal for a quick and simple install. 1/8" NPT ports are provided on each tube for connecting auxiliary sensors and retains the factory air temp sensor for a hassle-free installation.Custom Appearance: Finished in wrinkle-black powder coating and badged with a unique aluminum laser-cut aFe Power logo welded on for a custom look.
