Keep your BMW E46 cooling system leak-free with this 20-piece O Ring Kit. Specifically designed for M52/M54 engines, it supports models including 328i, 323i, 325i, 328i, and 330i. The kit provides a range of sizes to seal coolant hose connections and gaskets across the cooling circuit, helping prevent leaks, maintain optimal operating temperature, and extend the life of your cooling system.

Key benefits come from premium rubber seals that resist high temperatures and wear. Each O ring is crafted to form a tight, lasting seal under engine heat and pressure, reducing the risk of coolant loss and overheating. With OEM reference numbers included, this kit makes a reliable replacement option during rebuilds, maintenance, or routine service.
