What is a diverter valve and why would I upgrade it?

A diverter valve releases excess boost pressure from your turbocharger when you lift off the throttle. Upgrading to a performance valve like this Turbosmart unit can help it handle higher boost pressures more reliably than the stock valve, potentially improving turbo response and longevity.

Does this diverter valve come with everything needed for installation?

Yes, this Kompact EM valve is designed as a direct plug-and-play replacement. It installs directly into the factory location without requiring any additional adapters, hoses, or special assembly.

What is the difference between a plumb-back and a dual-port diverter valve?

A plumb-back design recirculates the bypass air back into the intake system before the turbo, which is generally quieter and often preferred for emissions compliance. A dual-port valve vents some air to the atmosphere for a sound, and some back into the intake.

About this part

Product Details

If you're looking to get the most out of your turbocharged BMW N55 engine, upgrading the factory diverter valve is a smart move. This Turbosmart Kompact EM Plumb Back VR9 valve is designed as a direct replacement for your stock unit, meaning you can unplug and unbolt the old one, then install this one without needing extra adapters or hoses. It's a true plug-and-play solution that works with a wide range of BMW models, including the 335i, 435i, and 535i.

This diverter valve is built from solid billet aluminum and features a high-temperature solenoid and O-rings, so it can handle the heat and pressure your turbo system generates. The Boost-Balance Valve Technology helps maintain consistent boost pressure by preventing leakage, which can lead to improved turbo response and a more reliable performance. The plumb-back design recirculates the air back into the intake system, keeping things quiet and emissions-compliant where required.

Installing this valve is straightforward since it's designed to fit right into the factory location. It's a well-built component from Turbosmart, a company known for its performance turbo parts, and it's a popular choice for BMW owners looking for a reliable upgrade.
