This alloy hard pipe fits to the throttle body and incorporates our high flow Blow off valve. This new valve fresh from our R&D department is the largest displacement valve that Forge have ever made ! Featuring a 50mm (2”) aluminium piston so that there are no issues with split diaphragms, we have not found the power handling limits of this valve yet ! The piston uses heat stabilised viton o-rings and high temperature Mobil 1 grease to ensure a long life with minimal wear and very long service intervals.

All parts are included in the kit, for your installation, along with comprehensive instructions.

2008 - 2013 E82 135i

N54 Chargepipe and BOV Kit:

All of the tuning in the world is only as good as the weakest link. More boost in your 135/335 is great! But you will soon learn that some of the factory hardware is not up to the task of handling that extra pressure. One of the first things to fail and cause a boost leak are the factory boost diverter valves. This allows boost to "leak" out of the intake stream and a loss of power from the engine. This ECS Tuning chargepipe upgrade includes a blow-off valve in place of the factory diverter valves. The BOV is higher quality than the diverter valves and will exit intake air to the outside instead of putting it back through the turbo system (which will reduce strain on the turbos). This aluminum chargepipe is also much more robust than the stock plastic factory pipe and the connection to the throttle body is stronger, eliminating another failure point of the stock pipe.

Built-in 1/8" NPT ports allow you to run an additional methanol injection kit (bungs included if you don't want use the ports).

This is a complete kit that includes everything you need to replace the factory chargepipe and diverter valves -

powedercoat chargepipe
ECS Tuning blow-off valve
multiple BOV springs to suit your vacuum/boost needs
vacuum plugs for the stock diverter valve hoses
silicone hose connection to intercooler piping
all hardware and hose clamps with instructions
