Ditch the brittle plastic. Upgrade to high-strength billet aluminum for ultimate reliability and style. 

The cooling system is the heart of your BMW, but the factory plastic coolant reservoir cap is a notorious weak point. Over years of heat cycles, the OEM plastic can become brittle and fail. The Bevinsee Billet Aluminum Coolant Cap provides a heavy-duty, permanent solution that ensures your engine bay looks as good as it performs.

Engineering Meets Aesthetics

Precision-machined from a single block of 6061-T6 billet aluminum, this cap is designed to withstand the high pressures of your BMW's cooling system without breaking a sweat.

  • Superior Durability: Replaces the weak factory plastic cover with CNC-machined aluminum that won't crack or warp under extreme engine temperatures.

  • Engine Bay Dress-Up: Finished with a premium anodized coating, this cap adds a professional, high-end look to your engine bay, replacing the dull, dingy yellow/black plastic

  • Factory Reliability: Designed to work perfectly with your original cooling system. By swapping your factory pressure-relief valve into this aluminum housing, you keep the precise OEM safety specs with a much stronger exterior.

  • Perfect Fitment: Utilizing the latest CNC technology, this cap offers a smooth, high-accuracy fit on a wide range of BMW models


Installation Note

This upgrade is a "cap shell" replacement. To install, simply snap the internal pressure-relief valve from your original plastic cap into your new Bevinsee billet aluminum housing. This ensures your cooling system maintains its factory-specified pressure relief settings.
