aFe BladeRunner hot charge pipe for the 2020-2021 Ford Explorer ST and Lincoln Aviator 3.0L EcoBoost. The TIG-welded 2-1/4in mandrel-bent aluminum pipe replaces the restrictive factory pipe, with smooth transitions that cut turbulence and pressure loss to add horsepower and torque. It includes a built-in CNC-machined aluminum blow-off valve adapter, stainless-steel SmartSeal clamps, 5-ply silicone couplings, and 1/8in NPT ports for sensors or water/methanol injection. Finished in textured red powder coat with a laser-etched aFe logo.
