AIRTEC by Turbosmart Kompact Shortie Plumb Back Uprated Recirculating Diverter Valve (DV) Direct-Fit for BorgWarner EFR, KKK & Ford EcoBoost Billet, O-Ring Sealed, 30+ PSI Fits Focus ST, F-150 3.5, Volvo T5, Astra VXR, Porsche 997 Turbo (x2)

AIRTEC x Turbosmart Kompact Shortie Plumb Back Bypass Valve is the go-to closed-circuit turbo recirculation solution for engines running BorgWarner EFR and KKK turbochargers, plus a wide range of Ford EcoBoost platforms. Swap out the fragile factory plastic unit for a compact, CNC-machined billet aluminium piston valve with O-ring sealing for rock-solid boost retention, crisper throttle pick-up and dependable performance at elevated pressure levels.

Built for tuned boost and daily reliability

• Direct bolt-in replacement for OE turbo bypass valve on BorgWarner EFR, KKK and many EcoBoost applications
• Precision billet aluminium body with a piston and O-ring for leak-free sealing under load
• Holds 30 psi plus with confidence, perfect for remapped and high-output builds
• Faster boost recovery between shifts and reduced risk of compressor surge
• Plumb back design keeps airflow recirculated for smooth, OEM-like manners without unwanted noise

Stock diaphragm-style valves often split or bleed under increased boost, costing you power. This Kompact Shortie recirculating DV fixes common boost leak issues and stabilises turbo response in a tidy package that fits like factory. Ideal if you are hunting for a turbo bypass valve upgrade, a dump valve replacement that keeps everything recirculated, or a performance DV for remapped EcoBoost, EFR or KKK setups.

Proven on our builds and customer cars

We have installed these valves in-house and out on customer vehicles. Feedback has been consistently excellent, with sharper boost response, improved drivability and peace of mind on tuned Ford EcoBoost, Vauxhall VXR, Volvo T5 and Porsche 997 Turbo projects.
