Oil filter housing and oil cooler gasket failure is one of the most common and costly issues on modern BMW engines. Over time, worn seals allow oil and coolant to leak, leading to belt contamination, cooling system failure, and in severe cases, catastrophic engine damage.

This oil filter housing gasket and oil cooler seal kit is designed as a direct replacement to restore a proper seal between the engine, oil filter housing, and oil cooler. Replacing these seals proactively helps prevent oil leaks, coolant contamination, belt slip, and unnecessary engine stress.
