LEYO Blow Off Valve Kit - Volkswagen Golf GTI / R (Mk7 / Mk7.5) / Audi S3 (8V)
LEYO's blow off valve kit replaces the factory electronic diverter valve on the EA888 Gen 3 turbo, a part known for diaphragm failures that leak boost. The multi-piece valve is CNC machined from 6061 billet aluminium with a hard anodised finish and uses a serviceable piston in place of the OEM diaphragm. It works with the factory electronics, holds boost more consistently and adds an audible vent sound.
Note: Suits petrol EA888 Gen 3 engines only, not diesels. LEYO offers a choice of valve springs to suit how far the car is modified, and uprated springs are sold separately. Installation by a professional is recommended.
Features
- 6061 billet aluminium body with hard anodised finish
- Serviceable piston design in place of the OEM diaphragm
- Direct replacement for the factory valve, works with OE electronics
- Helps prevent boost leaks for more consistent boost
- 360° adjustable boost connector
- Rated to around 447 kW (600 hp) with the uprated spring kit
- Laser etched branding
