BMW Engine Oil Pan Baffle and Aluminum Engine Oil Pan Upgrade Kit - 11137618512BFLKT

When BMW created the N20, they optimized every single metric that contributes to fuel economy - including oil flow. The N20 and N26 use a variable displacement oil pump for this reason, leading to slim oil pressure margins even during daily driving.

Coupled with a completely open oil pan - under hard cornering and braking - these margins vanish. In it's stock form, oil pressures dip down into the low-teens, sometimes even single digits during performance driving. While this isn't typically an issue for commuter cars, any more than a just a few instances of high RPM or heavy load with extremely low oil pressure will cause total engine failure.

This kit also includes all the required replacement hardware you will need for installing a new oil pan on your F2X/F3X rear-wheel drive N20/N26 powered BMW. This kit features an aluminum oil pan which can be installed in place of the factory-style composite version. This when combined with the oil pan baffle eliminates two problem areas that the N20/N26 rear wheel drive cars suffer from (oil pressure drops during sporty driving and a plastic pan that can become damaged from debris strikes)

Not included with this kit but highly recommended to have on hand is an oil change kit as well as new engine mounts. You will need to lower the subframe to replace the oil pan and this is the perfect time to replace them.

Disclaimer: While the oil pan baffle we've developed has been proven to drastically improve oil pressure under braking, cornering, and high-G's, there are other measures that need to be taken to ensure the N20 can live at a race-track. Adding up to 1 quart of additional oil (overfilled) has been found to help the longevity of N20s at the limit. Heat management, existing bearing wear, and bearing clearances are all factors that contribute to the health of an N20 on track. If you're planning to participate in endurance racing or extended track driving, we'd recommend investing in new engine bearings, additional cooling, a lower temperature thermostat, and additional oil control solutions such as an Accusump.
