Upgrade your Ford Focus RS with the Turbosmart Kompact Shortie Blow-Off Valve, engineered specifically to handle the high boost pressures of the RS’s EcoBoost engine. The factory plastic blow-off valve is known to leak, become brittle, and fail under increased boost—potentially causing performance issues and engine trouble. The Kompact Shortie solves these problems with a robust billet aluminium body and a strong, lightweight brass piston, individually matched for a precise fit. This design eliminates the need for piston O-rings, delivering superior durability, faster response, and reduced maintenance compared to typical aftermarket BOVs.

Choose from two versions to match your driving style:

• Plumb Back: Fully recirculating for discreet operation and OEM-like sound, ideal for those who want stealth performance.
• Dual Port: Split operation for quiet recirculation at low boost and aggressive vent-to-atmosphere sound at high boost—perfect for enthusiasts who want both performance and a rally-inspired sound.

The Kompact Shortie features enlarged ports for improved flow, supporting higher boost levels without compromise. It’s a direct replacement for the OEM valve, requiring no custom fabrication or special tools. Each unit is built for reliability and performance, making it a smart upgrade for any Focus RS owner seeking better boost control and long-term durability.
