Designed for the N13 1.6 petrol turbo engine, this precision CNC-machined alloy valve replaces the factory electronic recirculation unit to deliver sharper throttle response, a crisp turbo whoosh, and dependable performance even on remapped cars. We have fitted these on customer vehicles and the feedback has been outstanding for both reliability and sound.\u003c\/p\u003e\n\n\u003ch3\u003eWhy choose this valve\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eEliminates charge leaks caused by the stock valve’s rubber membrane, helping you hold requested boost and maintain consistent power.\u003c\/li\u003e\n  \u003cli\u003ePiston actuated design with no diaphragm to tear, engineered for long-term durability under heat and higher pressures.\u003c\/li\u003e\n  \u003cli\u003eKeeps the OEM electronic control strategy so drivability and ECU management remain as intended, with improved response.\u003c\/li\u003e\n  \u003cli\u003eInterchangeable springs included to suit standard, Stage 1 or more aggressive tunes.\u003c\/li\u003e\n  \u003cli\u003eDistinct vent-to-atmosphere sound for that authentic turbo note without compromising control.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePerfect for tuned and daily-driven cars\u003c\/h3\u003e\n\u003cp\u003eWhether your N13 is stock or running a remap, this upgrade is a proven fix for the common OE diverter failure that robs performance without always triggering a warning light. It is equally at home on UK roads, in hot weather traffic, or on spirited drives where heat and pressure expose weaknesses in the factory part.\u003c\/p\u003e\n\n\u003ch3\u003eHow it works\u003c\/h3\u003e\n\u003cp\u003eThis assembly replaces the original electronic recirc unit with a robust piston-based mechanism that uses a manifold reference line while retaining ECU-commanded actuation via the supplied solenoid. The result is fast, consistent valve operation under load changes, stronger sealing under boost, and a satisfying vent-to-atmosphere release on lift-off.\u003c\/p\u003e\n\n\u003ch3\u003eVehicle compatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eBMW 1 Series F20 and F21: 114i, 116i, 118i, 120i\u003c\/li\u003e\n  \u003cli\u003eBMW 3 Series F30: 316i, 318i, 320i\u003c\/li\u003e\n  \u003cli\u003eEngine: N13 1.6 turbo petrol\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eBox contents\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Atmospheric valve\u003c\/li\u003e\n  \u003cli\u003e1 x Aluminium connector\u003c\/li\u003e\n  \u003cli\u003e1 x Length of vacuum hose\u003c\/li\u003e\n  \u003cli\u003e1 x Uprated spring\u003c\/li\u003e\n  \u003cli\u003e1 x Electronic solenoid\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFitting and support\u003c\/h3\u003e\n\u003cp\u003eProfessional installation recommended.
