GrimmSpeed™ introduces the most complete and easy to use Subaru WRX, STi, FXT, and LegacyGT 3-Port Electronic Boost Solenoid available on the market. Our aftermarket boost controller allows you to raise the OEM boost levels in a quick and efficient manner. If you try to raise the boost on the weak OEM boost solenoid it will start to become unpredictable and unable to maintain proper and safe boost levels. Using our solenoid you are able to spool your turbo quicker and maintain a rock solid boost level. We have made our solenoid to withstand 120psi, way more than any Subaru will see.
Revolutionizing the Subaru boost solenoid market, we have created model specific install brackets that allow you to directly fit our Boost Solenoid into your Subaru for a factory fit. No more Zip-tying! We give you the factory fitment you have been waiting for.
Staying with the OEM fitment theme, our Boost Solenoid uses a Subaru style wiring harness so you can simply unplug your OEM solenoid and plug ours in. No more cutting the oem wiring and crimping wires together!
Also new to the Subaru boost solenoid market, we have used ultra low-profile hose fittings to keep the unit as small and clean as possible. The hose fittings are nickel plated brass so you don't have to worry about them snapping off like the plastic hose fittings!

GrimmSpeed was founded in 2006 to provide customers with innovative and highly engineered products.
The company's founder, Justin Grimm, has always had a passion for Subarus. Just like most enthusiasts, he was satisfied with his vehicle's performance stock, but could not resist the urge to see just how much more potential was left untapped. After a few years of perfecting his ideas and techniques on his own personal Subaru, Justin decided to turn his passion into a career. He immediately realized the niche market for Subaru aftermarket performance and founded GrimmSpeed, initially performing all of the work out of his own garage. As the demand for his own high quality products grew, he opened a new shop in St. Paul, MN. Enthusiasts quickly took to GrimmSpeed, and it became necessary to expand even further to a larger location. In January 2010 GrimmSpeed moved into a 6500 SQ FT shop in Minneapolis, MN. This move has given GrimmSpeed the opportunity to expand for years to come.
Due to the extreme weather conditions of Minnesota, GrimmSpeed has unique opportunities to test their products to ensure quality performance. This allows the engineers to take advantage of a very wide range of conditions for product testing. This enables GrimmSpeed to continuously perform research and development on all products and make revisions accordingly.
