aFe BladeRunner hot and cold intercooler tube combo for the 2020-2025 Chevrolet Silverado and GMC Sierra 1500 3.0L Duramax, plus the Tahoe, Suburban, Yukon, Yukon XL and Cadillac Escalade. The TIG-welded 2-1/2in hot-side aluminum tube and reinforced 2-3/8in cold-side silicone hose replace the restrictive factory plastic and rubber plumbing for cooler, smoother charge delivery and added power. It uses a factory-style billet aluminum quick-connect adapter with an o-ring seal, stainless-steel SmartSeal clamps, 5-ply silicone couplings, and 1/8in NPT ports in both the hot-side tube and cold-side hose for sensors or water/methanol injection. Finished in wrinkle black powder coat.
