Diverter Valve Upgrade Mini Cooper S R56, Peugeot 207 / 308 / 508 / RCZ & Citroen DS3 / DS4 / DS5 1.6 Turbo – GFB DV+ T9352

Direct-fit replacement for the factory solenoid-type diverter valve on 1.6 turbo engines. The factory solenoid is kept and the valve parts are replaced with metal ones, so the ECU keeps control and the air is recirculated.

• Keeps the factory solenoid and ECU control; replaces the plastic valve parts with an anodised billet aluminium housing and brass piston
• "Pilot-actuated" piston: the solenoid controls the air pressure that moves the piston, so it can open progressively
• Intended to give sharper throttle response (supplier-stated)

Fitment (supplier list, all 1.6 turbo engines): Mini Cooper S N14 R55/R56/R57 (2006–2010); Citroen DS3, DS4, DS5 1.6 THP 155 (2010–2012); Peugeot 207 1.6T 16V (2006+), 308 1.6T 16V (2007+), 508 1.6 THP (2010), RCZ 1.6 16V (2010).
