Forge BMW N13 1.6 Turbo F20 F21 Atmospheric Blow Off Valve (114i, 116i, 118i & 120i)
This Blow Off, or Dump valve, is for the BMW N13 1.6 Turbo engines that have the electronically controlled bypass valve. This engine can be found in the F20/F21 and F30 chassis badged as 114i, 116i, 118i, 120i and 316i, 318i and 320i It is recommended for any vehicle where the boost pressure has been increased by an ECU software upgrade and for unmodified vehicles operating in warmer climates, as a solution to the many failures that have occurred, where the original rubber diaphragm splits, which causes a loss of boost pressure. Unfortunately, the failure does not always result in a check engine light as the valve can still be blown open by the boost pressure, so you may not be aware that you are losing power due to this.
Our alternative is a fully engineered solution offering significantly improved reliability. Our valve is piston based with no diaphragm to fail, and of all aluminium construction. It replaces the original unit with a pressure/vacuum operated piston valve that still also retains the desirable OEM ECU control over valve actuation. Not only that the internal spring can be changed for either a stronger or weaker version depending on how much boost pressure you are running.
