If you’re looking to upgrade your Audi RS4’s performance, this reinforced silicone MAF hose is a solid choice. It’s designed specifically to connect the RS4 MAF to either the 2.7T or RS4 Y-Pipe, making it a straightforward drop-in replacement for that OEM hose. Trust me, I’ve seen the difference this makes in both fit and function.

What sets this hose apart? For starters, it features a larger inside diameter and a smoother surface, which means better airflow. This can really help your engine breathe easier, especially if you’re pushing it hard. Plus, the stiffer construction is a game-changer—it’s built to resist collapsing under pressure, which is something you definitely want to avoid when you’re pushing your car to its limits.

Made from high-quality automotive silicone, you can count on this hose for long-lasting reliability. It’s not just about looks; this material can handle the heat and stress of high-performance driving. The IDs are approximately 88 and 90mm, which makes it compatible with most 85mm MAFs available, including our Billet Aluminum MAF Housings. So, if you’ve got aftermarket upgrades, you’re in good shape.

It’s available in black, keeping it sleek and low-key under the hood. And don’t worry about the little details—we’ve included new hose clamps with your purchase, so you’re all set to install it right out of the box.
