Both carry our standard finish, a 2K clear coat with UV absorbers over a heat-resistant outer layer, because the engine bay runs hotter than anywhere outside the car and heat is what makes a clear coat yellow over time. For the large majority of owners that is the right choice. On Gloss you can also add our \u003ca href=\"https:\/\/carbonxtrem.com\/pages\/carbon%20fiber-vs-wet-carbon-what-s-the-difference#full-thermal-clear-coat\"\u003eFull Thermal Clear Coat\u003c\/a\u003e, where the heat-resistant formulation runs through every layer rather than the outer one alone, the most durable finish we offer for the bay. It costs more and is a deliberate choice for owners who want the longest life. The standard finish is not a lesser one.\u003c\/p\u003e\n\u003cp\u003eThe CarbonXtreme Carbon Fiber ECU Battery Terminal Cover replaces the factory plastic cover over the ECU and battery terminal on the BMW G80 M3, G82 M4, and G87 M2. You unclip the plastic piece and clip a finished, clear-coated carbon one in its place. It is a single piece, one of the small details that pulls a carbon bay together.\u003c\/p\u003e\n\u003cp\u003eBMW fits a plastic cover here and offers no carbon version of it. The only carbon BMW puts in the engine bay is the engine cover; everything else, this piece included, stays plastic unless you change it yourself. A carbon bay is built one small piece at a time.\u003c\/p\u003e\n\u003cp\u003eOn its own it is a small upgrade; it earns its place as part of the whole, when the panels around it are carbon too.

The pressure drives the air from the layup, so the weave stays even and the cover stays light and true. The few fine surface pinholes any weave can leave are filled before the clear coat goes on, far fewer than a hand-laid part needs.

What it does is refuse to leave a plastic cover sitting among carbon ones. It is an upgrade you feel rather than measure, the kind of detail the owner who notices would not leave undone.
