Replace your brittle plastic caps with high-grade, anodized billet aluminum.
The factory plastic A/C service port caps on most BMWs are often dull, prone to cracking, or simply disappear over time. The Bevinsee Aluminum A/C Line Cap Kit is the perfect engine bay upgrade, combining rugged durability with a high-end aesthetic. CNC-machined from aircraft-grade 6061-T6 billet aluminum, these caps provide a secure seal for your R-134a system while adding a touch of "motorsport" to your engine compartment.
