Instantly elevate the appearance of your engine bay with this real carbon fiber coolant tank cap cover, designed to fit directly over the factory plastic coolant reservoir cap across a wide range of BMW E and F chassis models. The factory plastic cap is prone to yellowing and discolouration from oil vapour and heat exposure over time — this carbon fiber cover conceals it entirely while adding a premium, high-texture finish that complements a performance-oriented engine bay. The high-gloss UV-resistant coating protects against oil vapour, high temperatures, and chemical corrosion, maintaining the lustre of the carbon weave for the long term. No tools required — simply clean the original cap surface and press fit the cover into place.

Features:

• Real carbon fiber construction with high-gloss coating – instantly upgrades the engine bay appearance over the factory plastic cap
• UV-resistant gloss coating protects against oil vapour, high temperatures, and chemical corrosion for long-lasting lustre
• Fits directly over the original plastic cap – protects it from yellowing and oil stain penetration without any permanent modification
• Tool-free installation – clean the original cap surface and press fit into place
