Upgrade your Ford Focus RS with the Turbosmart Kompact Shortie Blow-Off Valve, engineered specifically for the RS’s high boost pressures. The factory plastic blow-off valve is a known weak point, prone to leaks and cracking as it ages—especially with the RS’s standard 23 PSI of boost. The Kompact Shortie replaces this with a robust billet aluminium body and a precision-matched brass piston, delivering superior durability and responsiveness without the need for piston O-rings.

Choose between two variants to suit your driving style:

• Plumb Back: Fully recirculating for discreet operation. Delivers all the performance benefits of an upgraded BOV while maintaining a stock-like sound.
• Dual Port: Splits operation between recirculating and vent-to-atmosphere. Enjoy quiet performance at low boost and signature turbo sounds at high boost—perfect for those who want the rally-inspired character of the Focus RS.

Both versions feature enlarged ports for improved airflow, supporting higher boost levels without compromise. Installation is a direct replacement—no custom fabrication or special tools required.

Features:

• Direct fit for Ford Focus RS (EcoBoost)
• Billet aluminium construction for maximum strength
• Individually matched brass piston for optimal sealing and durability
• No piston O-ring required—less maintenance
• Available in Plumb Back (recirculating) and Dual Port (recirculating/vent-to-atmosphere) configurations
• Enlarged ports for increased flow

Includes everything needed for installation.
