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 2017-18 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.
