Aluminum Coolant Cap spece46

Aluminum Coolant Cap spece46CNC aluminum 1. 2 bar Cooling System Cap uses 100% original BMW internal components that have been recalibrated to vent at 1. 2 bar vs. the factory 2. 0 bar setting. Most modern cooling systems are calibrated at 1. 0 1. 2 bar to reduce stress on the plastic components, increasing the lifespan of the fragile plastic parts without affecting the performance of the cooling system. The top of the cap is CNC machined from 6061 aluminum, hard anodized black
