Forge Motorsport Recirc Ram Dump Valve MY01+
Made from billet aluminium, this recirculating diverter valve dumps the charge-air back into the air intake system keeping external noise to a minimum. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably.

Unlike single piston or diaphragm diverter valves, this uses counter balanced springs and dual pistons to prevent the valve from leaking air into the intake system at idle. This prevents our diverter valves suffering any of the failures associated with single piston and diaphragm type diverter valves.

Effectively does the same as the factory fit dump valve, but looks a hell of a lot nicer and is probably a lot more efficient!

Cost £160, immaculate condition (only a few weeks old) looking for £80 to include p&p.
