BMW B48 / B48TU Performance Oil Pan Baffle – 11138580122

Improve oil control during demanding driving with the STROM Motorsports BMW B48 Oil Pan Baffle, designed specifically for engines equipped with the later BMW 11138580122 oil pan.

Developed for performance, track and road-racing applications, this oil pan baffle is designed to help prevent low oil pressure during prolonged heavy braking by improving oil control within the sump.

Tested extensively under extreme conditions on STROM Motorsports B46 race cars, this is an ideal upgrade for BMW B48D and B48TU engines used in track cars, race cars and high-performance road builds.

Improved Oil Control Under Heavy Braking

During prolonged or high-G braking, engine oil can move aggressively inside the sump. In demanding motorsport applications, this movement can contribute to temporary oil pressure issues.

The STROM B48 oil pan baffle is designed to help control oil movement within the sump, reducing the potential for low oil pressure during extended braking events.

This makes it a particularly worthwhile upgrade for vehicles regularly used for:

• Track days

• Circuit racing

• Time attack

• Motorsport

• High-performance road driving

Developed & Race Tested

Rather than being designed purely as a theoretical upgrade, the STROM oil pan baffle has been extensively tested under extreme conditions on B46-powered race cars.

Multiple variations were tested during development to create a practical oil-control solution for demanding track use.

How to Identify the Correct B48 Oil Pan

BMW B48 engines can be equipped with different oil pan designs, so it is important to identify your oil pan before ordering.

The later 11138580122 oil pan has a noticeable small bulge on the bottom of the sump next to the oil drain plug.

If your oil pan has this bulge, this STROM 99.00037 oil pan baffle is the correct version.

If your oil pan does not have the bulge, you will generally require the STROM 99.00038 oil pan baffle, designed for the earlier BMW 11138611694 oil pan.

Oil Pan Compatibility

This version:

• Late BMW oil pan: 11138580122

• STROM baffle: 99.00037

Alternative version:

• Early BMW oil pan: 11138611694

• STROM baffle: 99.00038

Because BMW B48 engines may be found with different oil pans depending on production date and application, always visually inspect your oil pan and verify the BMW part number before ordering.
