Improved Racing's thermostat provides quick engine warmup, prevents overcooling, and delivers full oil cooling capacity on demand. Trusted by professional race teams around the globe, Improved Racing's thermostats have proven highly reliable, are backed by a lifetime warranty, and are made in the USA. Option to Use the Factory Oil Cooler and Lines The optional factory oil line adapter allows you to use the factory oil cooler lines for a simple, plug-and-play installation. For maximum performance, the factory oil cooler and lines may be replaced with an aftermarket cooler and AN lines using the AN adapter fittings (-10AN line size is recommended). Please note that some applications, such as most BMW SUV's, use a water-to-oil heat exchangers. These applications require plugging the coolant supply and return ports, as well as adding an external air-to-oil cooler and lines (factory or aftermarket). Please note the Oil cooler adapter cannot be used without an oil cooler.

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
