The aFe BladeRunner 2-1/2 inch Aluminum Hot Charge Pipe is a high-performance upgrade designed to enhance the intake system of the 2022–2023 Subaru WRX with the H4 2.4L turbocharged engine. Constructed from mandrel-bent aluminum, this charge pipe ensures smooth airflow transitions that reduce turbulence and minimize pressure loss, resulting in increased horsepower and torque. The pipe is finished with a durable textured red powder coating for corrosion resistance and aesthetic appeal. Included in the kit are stainless-steel SmartSeal clamps and a heavy-duty, 5-ply polyester reinforced silicone coupling, providing a secure and leak-free connection. A factory-style billet aluminum quick-connect adapter with an O-ring seal further guarantees a tight, durable fit.
This charge pipe is specifically engineered for the 2022–2023 Subaru WRX models equipped with the 2.4L turbocharged flat-four engine. It serves as a direct replacement for the factory hot charge pipe, offering a bolt-on installation that requires no modifications. The kit includes all necessary clamps, couplings, and the quick-connect adapter for a complete upgrade. Ideal for street and performance driving, this charge pipe enhances throttle response and overall engine efficiency while maintaining OEM-level reliability and fitment.
