Original BMW Catalytic Converter Holder Near Engine - 228i, 230i, M235i, M2, 3 Series, and 4 Series (2012–2021)

The Original BMW catalytic converter holder near engine is the bracket that supports the exhaust at the converter closest to the engine on F-chassis BMW 2, 3, and 4 Series cars and the M2. BMW's parts data gives a weight of 74 g and shows production starting in November 2011. The holder is made in Germany and sold individually, priced each. An exhaust holder carries the weight of the pipes and converter and limits how much engine and exhaust vibration reaches the body. When a holder breaks or gives out, the exhaust can move too much. You may hear clunking or rattling over bumps or under acceleration, feel vibration through the floor or seats, or find the pipes slowly pulling out of alignment.

Original BMW Parts carry a 24-month parts warranty.

This number replaces 18-30-7-621-016. BMW marks the change as exchangeable retrospectively, so the newer holder also suits cars that left the factory with the earlier part. BMW groups it under the F22 and F23 2 Series, F87 M2, F30, F31, F34, and F35 3 Series, and F32, F33, and F36 4 Series. Engine coverage includes the N20, N26, and B46 four-cylinders and the N55 six. BMW's data codes the holder for rear-wheel-drive cars.
