PRODUCT DESCRIPTION
This upgraded Forge blow-off valve for the Peugeot 308 GTI has been expertly manufactured and designed in the UK. Designed specifically for the Peugeot 308 GTI, this is a full atmospheric blow-off valve, so you get that fantastic "pshh" sound! This part replaces the original part with reference number 9808798580.
This alternative to the original part is an advanced engineering solution that provides significantly improved reliability. The blow-off valve is piston-operated, with no diaphragm to break, and is made entirely of aluminum. It replaces the stock unit with a pressure/vacuum-operated piston valve, while maintaining the original ECU's control over valve actuation.
Features:
Uses the best springs in the world for more precise and consistent operation.
All internal and external components of the blow-off valve are manufactured in the UK, which guarantees the highest quality and results in faster response times and longer service intervals.
The piston valve uses thermo-stabilized Viton O-rings.
Lubricated with Mobil1 high-temperature grease to ensure a long life with minimal wear and very long service intervals.
Super strong and fast-responding aluminum piston.
Fully serviceable and rebuildable in minutes with the valve repair kit.
Available in anodized black.
Unlike other valves on the market, the Forge turbo valve does not activate the engine warning light (CEM).
Lifetime warranty.
