RACING SPARK PLUG FOR M50/M52/M54 ENGINES
These spark plugs are recommended by BMW Motorsport for use in their DTC racing engines. We find a slight horsepower increase and greatly increased durability over the OEM road car spark plugs in competition use. We attribute the improvements to the fact that these spark plugs are designed for the high temperatures and cylinder pressures encountered in a racing engine. These spark plugs are a direct replacement and come pre-gapped just like the factory road car plugs.
Please note: these plugs are not for the S54 engine in the E46 M3, MZ3, or Z4 M

Sometimes a bad coil may just be a broken or damaged connector boot. This is especially true on cars with a leaking valve cover gasket where the oil has contamintated the rubber boot and the electrical parts inside. This boot can be replaced on its own without having to buy a whole new coil. This part is also useful if you purchased a coil that did not come with a new boot.

This is the replacement for the troublesome oil filter profile gasket on the M50, S50US, M52, S52, M52TU, M54, and S54 engines. The housing is separate from the engine block and in between there is this small profile gasket. The gasket shrinks over time which allows oil to seep out. In our own service shop, it's one of the most common service jobs we perform. One of the other common leak points is the VAN0S oil line and its seals. Since the line comes out with the oil filter housing anyway you might as well replace the line itself or at least the seals. On S54 engines (E46 M3, MZ3, Z4 M) there is a flanged head bolt going into the cylinder head, behind the thermostat cover. This holds the left side timing chain guide rail in place and if it's loose or falls out you could have a very serious engine failure to deal with. Make sure to check this bolt while you're replacing the oil filter housing seal. You only need to make sure it's tight. But if it's come loose you may want to replace the seal ring and use a small touch of oil-resistant thread sealer.
