A convenient alternative to hunting for genuine OEM

Genuine BMW brake cooling ducts (OEM #51118044701 / #51118044702) run roughly $70-150+ each when you can find them new. Our reproduction set gets you both sides, ready to install, without the search.

Please note: these are aftermarket reproductions, not genuine BMW parts. We know the OEM ducts are the higher-quality option — this set exists purely for convenience, so you don't have to track down genuine parts separately.

Disclaimer: All aftermarket parts may require minor trimming or adjustment for a perfect fit, even when designed to match OEM mounting points. Professional aftermarket installation recommended.
