Detailed Description

This Nissens engine oil cooler, part number 91359, is engineered as a replacement heat exchanger for BMW vehicles that require stable oil temperature control. By helping transfer heat away from the lubricant, it supports reliable operation of internal engine components under everyday driving and higher-load conditions. The aluminum core and conventional layout are selected for consistent thermal performance and service life. This part number 91359 is listed for applications including BMW M340i xDrive, BMW X5, and BMW 740i xDrive, along with other BMW models in the 2016-2024 range.

Compatible With BMW 840i, 840i Gran Coupe, 840i xDrive, 840i xDrive Gran Coupe, M240i, M340i, M440i, X3, X5, X6, X7, 540i, 740i, and Z4 applications depending on configuration. For select vehicles, the cooler mounts at the oil filter adapter; for others, the listing specifies without housing.

What It Helps Address

• Elevated engine oil temperature during normal or demanding driving
• Reduced oil cooling efficiency from a worn or leaking cooler
• Oil seepage at the cooler assembly area
• Service replacement needs on BMW oil filter adapter-mounted cooler systems
• Cooling system maintenance on vehicles with a without-housing oil cooler setup

Installation Notes and Tips

Verify the vehicle’s engine code, cooler location, and housing requirement before installation. This part is listed for two configurations: at the oil filter adapter and without housing, depending on application. Inspect mating surfaces, seals, and adjacent cooling components during service, and confirm fitment against the exact BMW model and year before ordering.

Quality Assurance

Nissens oil coolers are manufactured as quality heat exchangers and are backed by in-house testing to help meet strict performance standards. The brand’s testing process is used to support consistent fit, thermal performance, and long service life in replacement applications.
