This unit is perfect for the 2008-2011 BMW 528i and the 2009-2010 BMW 528i xDrive models. It’s a direct replacement for OE parts 18 40 7 596 876 and 18 40 7 563 732, so you know it’s going to fit like a glove. The design mimics the OE spun body, and that single laser fusion weld means leaks are less likely. Plus, it’s got a compact, low-mass design that boosts thermal efficiency, which is always a win.

And don’t sweat the installation. The included gaskets and hardware mean you won’t have to reuse any corroded factory parts. Just grab your tools, and you’ll have this installed in no time. It meets or exceeds those pesky Federal emissions requirements set by the EPA, so you can drive with peace of mind knowing you’re compliant with OBDII standards.
