aFe POWER BladeRunner 2.5in Red Aluminum Hot Side Charge Pipe for 2015-2021 Subaru WRX (2.0T) 46-20378-R

Fits 2015-2021 Subaru WRX Base, Limited, and Premium models (2.0T).

Improve the airflow and boost response of your FA20DIT engine with the aFe POWER BladeRunner hot side charge pipe. This upgrade replaces the restrictive factory plastic piping with mandrel-bent 2-1/2 inch aluminum tubing, providing a smooth transition that reduces turbulence and minimizes pressure loss. The result is a more efficient path from the turbo to the intercooler, outflowing the factory tube by up to 30%.

Engineered for durability under high boost, this kit features TIG-welded construction and a CNC-machined turbo adapter flange with an O-ring seal to ensure a leak-free fit. It also includes a 1/8 inch NPT port for easy installation of sensors or water-methanol injection nozzles. The assembly is finished in a textured red powder coating for superior heat and corrosion resistance, while the heavy-duty 5-ply polyester reinforced silicone couplings and stainless-steel T-bolt clamps provide the strength needed to handle increased temperatures and pressures.
