BMW G8X M2/M3/M4 Carbon Fiber Battery Terminal Cover

BMW G8X M2/M3/M4 Carbon Fiber Battery Terminal Cover – by Luminous Carbon

Even the smallest details make a difference. The Luminous Carbon Battery Terminal Cover for the BMW G87 M2, G80 M3, and G82/G83 M4 adds a subtle yet striking touch of carbon fiber to your engine bay. Designed to replace the dull factory plastic terminal cap, this upgrade enhances the look under your hood with genuine carbon fiber craftsmanship and a clean, high-end finish.

Made from real 2x2 carbon fiber weave, this cover is available in your choice of wet or dry carbon fiber, allowing you to match your other engine bay upgrades or overall build aesthetic. It installs in minutes with a perfect OEM-like fit.

Wet vs. Dry Carbon – Choose Your Finish

At Luminous Carbon, we offer both wet and dry carbon fiber construction to suit your preferences:

Dry Carbon Fiber (Pre-preg)

• Produced from aerospace-grade pre-preg carbon fiber, autoclave-cured

• Lightweight and ultra-rigid, with a clean matte or satin finish

• Ideal for track or performance-focused builds

• Superior strength-to-weight ratio

Wet Carbon Fiber

• Hand-laid carbon fiber with resin and topped with a high-gloss clear coat

• Heavier than dry carbon but delivers a deep, reflective finish

• More affordable, perfect for street or show builds

Both options are crafted using 100% real carbon fiber, not plastic overlays or hydro-dipped replicas.
