Perrin Performance is a Washington State brand that has built one of the deepest and most trusted Subaru WRX and STI performance parts catalogs in North America — covering intakes, intercoolers, turbo inlets, BOVs, pulleys, suspension, and dozens of supporting modifications. Perrin's parts are engineered and tested on Subaru platforms specifically, not adapted from generic applications, which gives them a level of fitment precision and performance validation that distinguishes them from more general-purpose brands. At MyPartsGuy.ca we carry the Perrin lineup, all priced in Canadian dollars with no import fees or brokerage charges.

Perrin also covers Subaru BRZ and Toyota GR86 applications, making them one of the few brands with comprehensive coverage across the full Subaru/Toyota performance ecosystem.
