Upgrade the turbocharger charge-air system in your Subaru WRX with the aFe BladeRunner hot side charge pipe. Designed for 2015-2020 Subaru WRX models equipped with the 2.0L turbocharged engine, this replacement pipe uses smooth mandrel-bent aluminum tubing to improve airflow through the hot charge tract. Reduced turbulence and pressure loss can help support improved throttle response, horsepower, and torque when paired with other suitable performance upgrades.

The aFe BladeRunner 46-20378-R features TIG-welded 2.5-inch aluminum construction, a CNC-machined turbo adapter flange, and heavy-duty five-ply polyester-reinforced silicone couplings. Stainless-steel T-bolt clamps provide secure connections, while the CNC-machined inlet flange is designed to help deliver a reliable, leak-resistant seal. The integrated 1/8-inch NPT port can be used for compatible sensors or water-methanol injection equipment.

Finished with textured red powder coating, the charge pipe offers added resistance to heat and corrosion while giving the engine bay a distinctive appearance. A laser-etched aFe POWER logo completes the design. The pipe is engineered to outflow the factory tube by up to 30 percent and is intended as a direct-fit performance upgrade for applicable Subaru WRX applications. Professional installation is recommended, and calibration or supporting modifications may be required depending on the vehicle configuration.
