Turbosmart Kompact Shortie Plumb Back – VR08 - Ford Focus RS MK3

Turbosmart Kompact Shortie Plumb Back – VR08 for Ford Focus RS Mk3

The Turbosmart Kompact Shortie Plumb Back – VR08 (Part No: TS-0203-1264) is a high-performance blow-off valve engineered specifically for the Ford Focus RS Mk3. Built to withstand the RS’s factory 23 PSI boost pressures and beyond, this upgrade eliminates the weaknesses of the factory plastic valve while improving durability, response, and reliability.

Why Replace the OEM Blow-Off Valve?
The standard plastic blow-off valve fitted to the Focus RS is prone to failure. Over time, OEM valves leak, become brittle, and eventually crack under stress—especially when boost pressure is increased. For enthusiasts looking to extract more power, the factory valve becomes a limiting factor.

Turbosmart’s Solution: The Kompact Shortie

• Billet aluminium construction – far stronger and more reliable than plastic.

• Precision brass piston – lightweight, durable, and individually matched to the valve body for a perfect fit.

• No O-ring required – piston design ensures superior sealing and long-term reliability.

• Enlarged ports – engineered to handle the airflow demands of the Focus RS at both factory and tuned boost levels.

Plumb Back Design
The Plumb Back version is fully recirculating, maintaining OEM-like sound levels while significantly improving performance and reliability. This allows you to enjoy the benefits of a Turbosmart valve without drawing unwanted attention—ideal for drivers who prefer a stealth performance upgrade.

Alternative Option: Dual Port
For those who want more character, the Dual Port version splits airflow between recirculation and vent-to-atmosphere, delivering subtle operation during daily driving and a distinctive turbo sound under high boost.

Direct Fit Upgrade
The Kompact Shortie is a direct OEM replacement with no need for fabrication or special tools, making it one of the most straightforward and effective performance upgrades for the Focus RS Mk3.
