INCLUDES: Upgraded metal Mickey Mouse flange + O-rings for both N52/N51 (28i) and N54/N55 (35i) engines. This is the only solution on the market that comes with BOTH O-rings, so there’s no guesswork and it fits flush. The N54/N55 use the thicker O-rings, while the thinner O-ring—already pre-installed on the flange—is for the N51/N52. You get both included!

Fitment: Compatible with BMW engines, including N20, N52, N53, N54, and N55, as well as models like 135i, 325i, 328i, 330i, 335i, Z4, 528i, and more. Suitable for 2.0L engines and beyond.
