American tuning parts with a Subaru focus

GrimmSpeed is an American brand especially well known in the Subaru community, where its parts are popular on the WRX, STI and BRZ, among others. The range also covers other popular turbocharged cars. The brand develops parts that solve concrete challenges when an engine is tuned: better flow in exhaust and intake, lower temperatures and more precise boost control. The focus is on fitment and quality, so the parts can be installed without major modifications and stand up to hard use.

GrimmSpeed’s key products

Exhaust parts are a large part of the range, including catback systems, downpipes, up-pipes and manifolds that improve flow after the turbo and give a more distinctive sound. Intercoolers lower the intake air temperature, helping the engine deliver consistent power. GrimmSpeed’s electronic boost control solenoids are used to control boost more precisely together with a tuned engine management. You’ll also find oil catch cans, turbo heat shields and other engine bay parts. See each product for vehicle fitment.

Frequently asked questions

Does a GrimmSpeed downpipe require a tune?

On many turbo cars it is recommended to adjust the engine management when the downpipe is replaced, so boost and fuelling match the new flow. Check the description on each product.

What does an oil catch can do?

An oil catch can collects oil and vapours from the crankcase ventilation before they are routed back into the intake. This reduces oil deposits in the intake and intercooler.
