This new generation oil is made with a quality synthetic base and includes a molecular friction modifier for reduced friction and wear. It also glows under UV light so leaks can be easily traced! This unique oil contains a fluorescent green chemical friction modifier to smooth out hard metal surfaces, reducing overall engine wear and heat due to friction. Tests have shown a reduction in friction coefficient of as much as 15%! MolyGen oil is also a great choice for modern turbocharged engines which produce much more heat. The kit contains: Seven Quarts of Liqui Moly MolyGen Engine Oil Oil Filter Kit Drain Plug with Crush Washer

This is the replacement OEM oil filter kit for the S54 engine, as used in the E46 M3, Z4 M Roadster and M Coupe, as well as the 2001-2002 MZ3 M Roadster/Coupe (with S54 engine). This is the complete oil filter kit - filter, large o-ring for filter housing cover, small o-ring for bolt seal, flat washer for bolt, and copper seal ring for the drain bolt. It's everything you would need to complete an oil change - minus the Castrol 10W60 oil of course, which we sell at a great price. This kit is manufactured by Mahle - the original supplier to BMW for the 11427833769 BMW filter (factory filters come with the Mahle part number OX 187 printed on the cap).

Why Mahle over Mann? In the past we have sold a few different oil filters for the E46 M3 and S54 engines. But Mahle is the true OEM supplier for this part number. It fits perfectly and is the exact replacement part at nearly the same price as the slightly different Mann filter (and less than the factory BMW filter). For more detail, click here.

This filter fits the following BMWs:
2001-2006 E46 M3
2001-2002 MZ3 - M Roadster & M Coupe (S54)
2006-2008 MZ4 - M Roadster & M Coupe
