Charge Pipe Kit

The GrimmSpeed Charge Pipe Kit is engineered to replace the restrictive factory plastic charge pipe on the FA20-powered 2015-2021 Subaru WRX. This kit features larger diameter, CNC mandrel-bent aluminum tubing with smooth, gradual transitions from the turbo adapter to the intercooler. The increased tubing diameter and large radius bends reduce restriction for charge air, resulting in improved performance and decreased turbo spool time. Constructed from US-sourced 6061 aluminum, the tubing and turbo outlet adapter are designed for both lightweight strength and heat rejection. Custom-formed silicone insulates against the hot turbo area, while the aluminum further combats heat in the charge air. A CNC-machined turbo flange with a custom O-ring design addresses a common failure point found in other aftermarket charge pipes. *Fitment with some aftermarket radiators may require the use of a slimmer radiator fan setup.
