If you’re pushing your BMW 335i or 135i to the limits, you know the factory diverter valves can be a real bottleneck, especially when you’re cranking up the boost. That’s where the Evolution Racewerks Diverter Valve Charge Pipe comes into play. Born from the demands of the Evolution Racewerks 135i Time Attack program, this isn’t just another shiny piece of aftermarket bling; it’s a serious upgrade that tackles a common issue head-on.

Let’s get into the nitty-gritty. The stock diverter valve charge pipe has a sound baffle that’s supposed to smooth things out, but in reality, it creates turbulence that messes with airflow. We’re talking about a real drag on throttle response and turbo lag. By ditching that baffle, this charge pipe lets your intake air flow freely, which means quicker throttle response and less lag when you hit the gas. You’ll feel the difference when you’re merging onto the highway or taking those tight corners.

Crafted from lightweight, high-grade 6061 aluminum, this charge pipe is built to last. The 3-inch piping is matched perfectly to the throttle body, ensuring a snug fit that won’t leak. Plus, the precision CNC machining on both the throttle body and MAP sensor flanges means you’re getting a reliable connection every time. And let’s not forget those beaded ends and T-bolt clamps—they’re designed to keep everything secure, even when you’re pushing some serious boost.

Installation? It’s straightforward. You’ll get all the hardware you need, so you can get back on the road (or track) without a hitch. And since it’s developed under the tough conditions of racing, you know it’s up for the challenge.

Here’s a quick rundown of what you’re getting:

• Boosts throttle response and cuts down on turbo lag.
• Works with both factory and aftermarket diverter valves.
• Lightweight yet robust 6061 aluminum construction.
• Perfectly matched 3” throttle body piping.
• Retains the factory-style O-ring throttle body lock flange.
• Precision CNC machined flanges for a leak-free fit.
• Easy connection and disconnection for maintenance.
• Includes all necessary hardware for a complete install.
• Developed in the heat of racing, so you know it’s reliable.
• Comes with a limited lifetime warranty for peace of mind.

It’s compatible with the BMW 335i N54 models from 2009 to 2012, and if you’ve got a 135i from the same years, you’re in luck too. Just keep in mind that the images are for marketing purposes and the actual product might look a little different.

In short, if you’re serious about performance and want to get the most out of your BMW, this charge pipe is a no-brainer. It’s a straightforward upgrade that tackles a common problem and lets you unleash the full potential of your ride.
