aFe BladeRunner hot and cold charge pipe kit for the 2020-2023 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD 6.6L L5P Duramax diesel. TIG-welded 3in hot-side and 3-1/2in cold-side mandrel-bent aluminum pipes replace the restrictive factory plastic plumbing, smoothing flow between the turbo and engine for lower charge temperatures and added power. The kit includes factory-style billet aluminum quick-connect adapters with o-ring seals, stainless-steel spring-loaded T-bolt clamps, 5-ply silicone couplings, and 1/8in NPT ports for sensors or water/methanol injection. Finished in wrinkle black powder coat.
