This kit from Active Autowerke replaces the weak plastic charge pipe with a new aluminum part, secured with a high-quality silicone couple. When you're building a high-powered turbocharged engine, or even just looking for peace of mind on a stock application, durability modifications are just as important - if not more important - than adding power. If your charge pipe fails, it results in a huge vacuum leak that sends your ECU into limp mode, diminishing performance significantly. Don't wait - upgrade your charge pipe today!
This product fits the following BMWs:
2016+ F87 M2
2014+ F22 M235i
2012+ F30 335i
2014+ F32 / F33 / F36 435i

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 doesn’t 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.
