Original BMW Ignition Coil Cover with Vacuum Reservoir for BMW 320i, 328i, and 528i (2012–2013)

Sitting over the ignition coils on the N20 four-cylinder, this Original BMW ignition coil covering is the engine cover for the 2013 BMW 320i and 328i and the 2012–2013 528i, and it carries the vacuum reservoir for the vacuum-actuated wastegate system. BMW calls it the ignition coil covering, while most owners know it as the engine cover. The built-in reservoir means it is part of the turbo's wastegate control, not trim alone. BMW gives its weight as 1.4 kg (3.2 lb), and production of this number began in September 2011. It is made in Germany and sold as one piece. Like any engine cover, it also shields the top of the engine from dust and debris, reduces engine noise, and gives the bay a finished look.

Original BMW Parts carry a 24-month parts warranty.

The cover and the vacuum reservoir come as one part, so replacing the cover also replaces the reservoir that serves the wastegate. That makes this a functional part on the N20, unlike a purely decorative cover. Confirm that your car has the N20 engine and check the fitment table before you order.
