Charge Pipes & Turbo Inlets for BMW 1 Series E82 (2008-2013)

The factory BMW charge pipes are prone to cracking, as they are made from brittle plastic. Here at Turner, we sell several brands of replacement charge pipes that are typically made from cast aluminum. We recommend upgrading to hard charge pipes even on stock forced induction vehicles to avoid cracking - we've seen cracking occur on high mileage cars running stock power just as frequently as we do with high horsepower builds.

When adding boost to the N54 engine, it's important to consider effects throughout the rest of the system. Additional boost can overwhelm the stock BMW diverter valve system and lead to boost leakage, or boost spikes, and lost horsepower. With the factory components in place it's hard to maintain consistently high boost levels. Instead of the weak plastic components of the stock system, Active Autowerke uses a CNC-machined and mandrel-bent aluminum tube with a Venturi blow-off valve in place of the original diverter valves. The blow-off valve dumps overboost into the atmosphere for that distinctive turbo 'whoosh' sound. The single AA BOV is over-sized for the N54 application - taking the place of the two small diverter valves, and verified to handle over 600hp. With the BOV acting properly your turbos and other components are protected from compressor surge caused by excess pressure build-up.

We like the Active BOV better than other forms of diverter and BOV kits because it's tried and true - AA was the original turbo BMW tuners and their experience is second to none. That's why they took the time to engineer their kit to fit perfectly, using the OE-type connector to the throttle body, and high-strength silicone to the lower intercooler tube. Each connection is a tight, leak-free seal. The kit comes complete with the discharge tube, vacuum plugs for the stock hoses, and instructions. The tube is powdercoated in black and with a wrinkle finish for an OE appearance.

One major weak point in the N55 turbo plumbing is the stock upper chargepipe from the intercooler outlet to the intake manifold. The original N55 charge pipe is made from a weak plastic and can fail with even stock boost levels. The most common problem is a crack that develops along a seam where the pipe connects to the throttle body. Any crack here is bad as it creates a massive vacuum leak and the engine electronics will put the car into limp mode. If you don't want to be sidelined there is a very simple fix - the Active Autowerke N55 charge pipe.

This aluminum pipe is much stronger and more durable and nearly indestructable for the N55 application. It uses a CNC-machined factory-style connection and o-ring to the throttle body to ensure a tight and leak-free seal. The piping is a consistent 3" diameter for better flow and an improved throttle response. AA has included a raised boss with two ports should you choose to add a water/meth injection system later. The factory MAP sensor installs in the same location and the pipe is powdercoated black for a factory-type appearance.

With a stronger pipe you don't have to worry about the infamous chargepipe crack and lost boost levels and horsepower. All of the boost in the world is useless if it's leaking so using beefed up components in place of the weak factory pieces is the smart way to consistently high power output.

This item fits the following BMWs with the N55 engine:
2011-2012 E82 BMW 135i
2011 E90 BMW 335i 335xi 335i xDrive - Sedan
