    Founded in 2006, GrimmSpeed has established itself as a renowned name in the realm of performance parts, driven by a commitment to innovation and excellence. This company, led by a team of ardent car enthusiasts, was born out of a passion for delivering exceptional aftermarket products. Initially focused on Subaru WRX, GrimmSpeed's expanding team and engineering expertise have propelled it into catering to Mitsubishi, Ford, MazdaSpeed, and Hyundai markets.

    The journey began humbly, operating out of a single-stall townhouse garage in Maplewood, Minnesota. Over time, GrimmSpeed has transformed from a garage startup into a thriving business, offering a diverse range of high-quality products designed to elevate vehicle performance. From intercoolers and exhaust systems to intakes, gaskets, engine pulleys, phenolic spacers, and boost controllers, GrimmSpeed has emerged as a trusted name for automotive enthusiasts.

    GrimmSpeed's decision-making process is guided by three fundamental principles:

    1. Innovation: Innovation is the cornerstone of GrimmSpeed's ethos. Every project undertaken by the company is required to feature at least one groundbreaking element. Whether introducing novel concepts or enhancing existing products, the team at GrimmSpeed is driven by an unwavering passion for creating products that not only function effectively but also leave a lasting impact on the enthusiast community.

    2. Keeping Jobs in America: GrimmSpeed is on a mission to contribute to the revival of manufacturing in the United States. A substantial portion of the company's manufacturing activities occurs within the country, reflecting its commitment to showcasing America's manufacturing prowess to the world. Most of GrimmSpeed's partners are conveniently located in Minnesota, many of them just an hour's drive away. For the company, it's not just about profit margins; it's about making a statement that high-quality products can still be produced on American soil.

    3. Customer Service Excellence: Recognizing the varying standards of customer service in today's world, GrimmSpeed has set out to redefine customer service. When dealing with GrimmSpeed, customers can expect a service that embodies honesty, transparency, and integrity. In the face of product delays, GrimmSpeed refuses to offer vague assurances but instead provides customers with the most up-to-date information available. Should customers require assistance with product installation, they will find GrimmSpeed just a phone call or email away, ready to assist until the issue is resolved. Keeping promises is non-negotiable for GrimmSpeed; when the company commits to calling back, customers can trust that the call will indeed be made.

    Here are a couple featured parts that really show GrimmSpeed's commiment to quality:

    Grimmspeed is famous (well famous in the subaru world) for their Bypass Valves. These come in Black or Red and do not require tuning. 

    Recently GrimmSpeed expanded thier line up of performance parts by adding WRX turbochargers.
