The GrimmSpeed Charge Pipe kit replaces the restrictive plastic stock unit on the FA20 powered WRX with larger diameter CNC mandrel bent aluminum tubing and custom formed silicone.  The increased diameter 2.5in tubing and large radius bends decrease restriction for the charge air, which results in increased performance and decreased time to spool.  Beautiful texture black powdercoat, a subtle screen printed GrimmSpeed logo, and hidden silicone top off the aesthetics of the GrimmSpeed Charge Pipe and provide an upgraded OEM-like appearance.

  • Tubing and turbo outlet adapter constructed of US sourced 6061 aluminum
  • Smooth gradual transitions from the tapered turbo adapter, all the way to the intercooler
  • Silicone used to insulate against the hot turbo area, aluminum used to further reject heat from the hot charge air
  • CNC machined turbo flange designed for custom O-ring, preventing a common failure of other aftermarket charge pipes
  • Does not unnecessarily relocate bypass valve, reducing components and making installation faster and easier

*Fitment with some aftermarket radiators may require the use of a slimmer radiator fan setup

Quick shipping, great product

Finish is smooth, all hardwood included. Removal of one radiator fan, bottom engine panel required. Take care to not damage sensors near turbo inlet hose when removing old pipe. Secure tmi side clamps with strong torque. Nice look in the engine bay, excellent throttle response and boost numbers look fantastic. Definitely a must modification, many thanks to Grimmspeed.

Best Qaulity!

Installed on my 2018 WRX - Excellent quality, perfect fit, looks fantastic! I previously ordered another charge pipe from another company > (AE?) don't bother! My Subaru dealer tech warned me after the fact not to use the other company, I didn't know any better at the time, now I understand why other inferior charge pipes blow out seals!! GrimmSpeed is the ONLY one recommended from the guys with experience.
