Cover up the lackluster plastic caps that come on your factory BMW (B85 Engine) with a cap machined from solid aluminum.  The caps are offered in three common colors to add color to the engine bay.  The units install easily within minutes with no tools required.

Current known fitment: (G20) M330i/M340ix, (G26) M440i, (G42) M240i, (G22/G23) M440, and (G29) Z4.

Anodized parts can potentially fade over time due to engine bay heat.
