When it comes to upgrading your BMW's charge pipe, you want something that’s built to last, right? Evolution Racewerks gets it. A lot of other brands out there use these silicone hose connections for their throttle body setups. But let’s be real—those connections can be a bit dodgy. The throttle body lip is too short, and without proper beads, you're just asking for trouble when the boost kicks in. It might be the quick fix for some, but it’s not the way to go if you want reliability.

What Evolution Racewerks has done is pretty smart—they replicated the factory-style connection for their diverter valve pipe. It’s not just about slapping on a part; they’ve put in the time and resources to make sure it fits right and works better. So, if you’ve ever turned up the boost with a tune and watched your factory charge pipe crumble under pressure, you’ll appreciate this upgrade.

Made from 100% 6061 high-grade aluminum, this charge pipe is not only tougher but also designed to flow better. You’ll notice a difference in throttle response and turbo lag, thanks to the smooth bends and minimal obstructions in the piping. The upper pipe is 3 inches in diameter, which is a step up from the factory’s 2.5 inches. This means more airflow and less restriction, which is exactly what you want when you’re pushing your car to its limits.

One of the standout features is the throttle body flange. Evolution Racewerks was the first to replicate this for the N54 charge pipe, and they’ve brought that same attention to detail to the N55. The connection uses an O-ring sealed with a C-clip, making it not only secure but also super easy to install and remove. During testing, they pushed it up to 25 PSI without any issues—though they stopped there because the intake pipe blew off before they could go higher. It’s built to handle a lot, and you can trust that it won’t let you down.

And let’s talk about the MAP sensor. If you’ve ever had a boost leak because of a silicone hose, you know how frustrating that can be. Evolution Racewerks has you covered here too. They CNC machined their own MAP sensor flange that uses the same factory O-ring seal, ensuring a leak-free connection. It’s these little details that make a big difference.

This charge pipe kit comes with both the upper and lower charge pipes, so you’re all set for installation. Here’s a quick rundown of what you can expect:

• Improved throttle response and reduced turbo lag.
• Lightweight yet durable 6061 aluminum construction.
• Replaces the weak factory plastic pipe that can’t handle the heat.
• 3" piping for maximum airflow.
• Factory-style O-ring throttle body lock flange for secure fitment.
• CNC machined MAP sensor flange for a solid seal.
• Beaded ends and T-bolt clamps to keep everything in place under boost.
• Includes a silicone hump hose for flexibility.
• Compatible with the factory electronic diverter valve.
• All necessary hardware for a complete install is included.
• Backed by a Limited Lifetime Warranty.

As for fitment, this kit is designed for the BMW 435i xDrive with a manual transmission from 2014 to 2016. Just a heads up, though—this product is meant for off-road use only and isn't legal for pollution-controlled vehicles on public roads, especially in California.

So if you're looking to upgrade your BMW’s charge pipe and want something that’s going to hold up under pressure, this is the way to go. Trust me, you won’t regret it.
