Save money by repairing only the damaged component instead of purchasing expensive cooling assemblies.

Built from aluminum, this adapter holds up to the heat and vibration inside the engine compartment. The model number BOP40 ensures compatibility with thousands of vehicles, giving you confidence before you buy. You get a direct replacement that bolts on easily, keeping your maintenance routine straightforward.

Here is what makes this adapter a smart choice for your garage:

• Direct Replacement: The BOP40 design fits into existing ports to restore proper sealing.
• Aluminum Body: The metal construction resists corrosion and remains sturdy under thermal stress.
• Broad Fitment: Compatible with numerous BMW series and chassis codes for versatile repairs.

Verify your engine bay configuration before installation. This adapter acts as a precise substitute for original bungs found across many BMW models. Slip this into place during your next tune-up to maintain healthy operating temperatures.
