Founded in 2006 in a Maplewood, MN garage, GrimmSpeed began as a group of Subaru enthusiasts porting and polishing intake manifolds. Since then, they've grown into a full-fledged engineering and manufacturing facility in Minneapolis, yet are still rooted in innovation, American-made quality, and exceptional customer service.

Focusing on Subaru performance—while also supporting Mitsubishi, MazdaSpeed, Ford, VW, and Hyundai—GrimmSpeed designs and produces high-quality intercoolers, cold-air intakes, exhaust components, gaskets, pulleys, phenolic spacers, electronic boost control systems, chassis braces, and more. Every product emphasizes reliability and system integration, so they work harmoniously to provide real-world gains.

Guided by three pillars—pioneering innovation, supporting U.S.–based manufacturing, and delivering the customer service enthusiasts deserve—GrimmSpeed remains deeply committed to its core values. With passion-driven engineering and a growing community of driven Subaru owners, GrimmSpeed crafts performance gear that sparks both power and pride.
