Priced in CAD • No duties • No brokerage fees • Fast shipping across Canada
GrimmSpeed is a Colorado-based Subaru performance specialist with one of the most respected product lines in the WRX/STI community — their EBCS (Electronic Boost Control Solenoid), turbo inlet hoses, cold air intakes, and intercooler systems are trusted by enthusiasts from Stage 1 street builds to full competition setups. GrimmSpeed's engineering is purpose-built for Subaru platforms, not adapted from generic designs. At MyPartsGuy.ca we carry the GrimmSpeed lineup, all priced in Canadian dollars with no import fees or brokerage charges.
The GrimmSpeed EBCS is one of the most popular single bolt-on modifications for WRX/STI owners — it replaces the factory boost control solenoid with a higher-flow, more responsive unit that improves boost response and stability, often complementing a COBB Accessport Stage 2 tune.

Frequently Asked Questions
What does the GrimmSpeed EBCS do?
The factory boost control solenoid on WRX and STI engines has limited flow capacity that can become a restriction as boost levels increase. GrimmSpeed's EBCS replaces it with a higher-flow unit that allows the ECU to more precisely and rapidly control boost pressure. The result is improved boost response — faster spool and more consistent boost pressure across the RPM range. It's typically one of the first modifications recommended alongside a COBB Stage 2 tune.
GrimmSpeed vs Perrin for WRX intake?
Both produce quality intakes for WRX/STI. GrimmSpeed's cold air intake is known for a slightly more aggressive sound and good power delivery. Perrin's SF intake is respected for its high-quality construction and fitment. Both pair well with COBB Accessport tuning. Choose based on which fits your budget and which other GrimmSpeed or Perrin components you're running — pairing components from one brand simplifies troubleshooting.
