If you're serious about pushing your BMW 335i or 135i to its limits, the Evolution Racewerks Diverter Valve Charge Pipe is a game changer. I’ve had my fair share of experiences with stock parts, and let me tell you, those factory diverter valves just can’t keep up with the demands of high boost applications. They tend to falter when you really need them to perform, which is why I made the switch to this charge pipe.

What I love about this product is how it tackles one of the biggest issues with the factory setup: airflow. The stock diverter valve charge pipe has this annoying sound baffle that splits the airflow and creates turbulence. That turbulence? It slows down your charge intake air velocity, which means sluggish throttle response and more turbo lag. By ditching that baffle, the Evolution Racewerks charge pipe smooths out the airflow, which translates to quicker throttle response and a noticeable reduction in turbo lag. You’ll feel the difference immediately.

Now, let’s talk about the build quality. This charge pipe is made from lightweight, high-grade 6061 aluminum and features throttle body matched 3” piping. It’s precision CNC machined, ensuring a leak-free connection to the throttle body and MAP sensor. Plus, it retains the factory-style O-ring throttle body lock flange, so you don’t have to worry about any compatibility issues. The beaded ends and T-bolt clamps are a nice touch too, preventing the intercooler piping from blowing off when you crank up the boost.

For those of you who are considering methanol or nitrous injection down the line, this charge pipe comes equipped with a 1/8” NPT bung. It’s perfect for easy installation of injectors, and it even comes with a plug if you’re not ready to dive into that yet. It’s all about flexibility and future-proofing your setup, right?

To sum it up, this charge pipe was developed under the harsh conditions of racing on the Evolution Racewerks 135i race car. It’s designed to handle the heat and pressure of serious performance driving. And with a limited lifetime warranty, you can rest easy knowing you’ve made a solid investment.

• Increases throttle response and decreases turbo lag.
• Compatible with factory diverter valves or aftermarket options.
• Includes all necessary hardware for a complete installation.
• Fitment for BMW 335i Twin Turbo N54 Engine (2006-2008).

Just a heads up, the images you see are for marketing purposes, so the actual product may vary a bit. But trust me, it’s worth it. If you’re ready to unleash the full potential of your BMW, this is the piece you need.
