GrimmSpeed was founded in 2006 to provide customers with innovative and highly engineered aftermarket products. On a more personal level, we are a group car enthusiasts who are working our passions in the lovely city of Minneapolis, Minnesota. Our bread and butter started out anything Subaru. However, after growing our team and engineering expertise, we started developing products for Mitsubishi, Ford, MazdaSpeed, and Hyundai markets. We are a true garage start-up (single stall townhouse garage in Maplewood, Minnesota) and we've been lucky enough over the years to be able to turn it into exactly the business we had dreamed....actually, much more. We have a wide breadth of product offerings including; intercoolers, exhausts, intakes, gaskets, engine pulleys, phenolic spacers, boost controllers, and many more.
Universal items are not application specific and may or may not suit your vehicle. Some items may be suitable but are listed as universal (ie wheel nuts, oil filters) and In some circumstances a product may not fit automatically but can still be used with some modification (ie. catch can/gauge pod etc.). Be sure to check if the product is right for you or ask us for assistance before purchasing. Filter universal products by selecting “Show Universal Products” from the filter products menu.
