This improved Forge dump valve for the Peugeot 308 GTI has been manufactured and designed by experts in the UK.
Designed specifically for the Peugeot 308 GTI, this is a fully atmospheric dump valve, so you can enjoy that fantastic "pshh" sound! This part replaces OEM part number 9808798580.

This alternative to the original part is a fully engineered solution to provide significantly improved reliability. The dump valve is piston based, with no diaphragm to break, and is constructed entirely of aluminum. It replaces the stock unit with a pressure/vacuum actuated piston valve, while retaining the stock ECU's desirable control over valve actuation. 

Features:

• Use of the world's best springs for more precise operation and consistency.
• All internal and external components of the dump valve are manufactured in the UK, ensuring the highest quality and resulting in faster response times and longer service intervals.
• The piston valve uses heat-stabilized Viton O-rings.
• Lubricated with high temperature Mobil1 grease to ensure long life with minimal wear and very long service intervals.
• Super durable and responsive aluminum piston
• Fully repairable and rebuildable in minutes with the valve repair kit.
• Available in black anodized
• Unlike other valves on the market, the Forge turbo valve does not produce a check engine light (CEM).
• Lifetime warranty.
