This part replaces the original plastic element and brings complete visual consistency to the engine compartment, from the intake cover to the engine cover. Whether you drive a G80 sedan, G81 Touring, G82 coupe, or G83 convertible, you immediately transform the look of your engine bay the moment you open the hood. A detail? Perhaps. But it's precisely the one people notice when they open the hood in front of someone who knows the car.\u003c\/p\u003e\n\u003ch3\u003eA design that extends the M Performance pack\u003c\/h3\u003e\n\u003cp\u003eThe original expansion tank is the only translucent white element in the middle of an entirely black and carbon engine bay. By installing this \u003cstrong\u003ecarbon coolant reservoir cover\u003c\/strong\u003e, you eliminate this visual break and unify the whole: engine cover, intake cover, strut tower brace, and reservoir finally share the same weave. On an M3 G80 equipped with the factory carbon pack, the consistency is complete; on a version without carbon options, it's the first part to install to start the theme.\u003c\/p\u003e\n\u003ch3\u003eEasy installation and everyday protection\u003c\/h3\u003e\n\u003cp\u003ePre-formed according to the original dimensions, this cap mounts as a direct replacement for the original cap in less than 10 minutes, without any special tools. You unscrew the old cap, screw in the new one, and the seal of the reservoir remains fully ensured by the original gasket. The cap also protects the reservoir against heat buildup and hydrocarbon splashes on a daily basis. Immediate maintenance with a microfiber cloth.\u003c\/p\u003e\n\u003ch3\u003eCarbon fiber quality and available finishes\u003c\/h3\u003e\n\u003cp\u003eThis part is molded in \u003cstrong\u003egenuine pre-impregnated carbon fiber\u003c\/strong\u003e under pressure for maximum rigidity and low weight. The high-gloss anti-UV polyurethane varnish preserves the shine of the weave against UV rays, engine thermal variations (up to +110°C), and hydrocarbons.

Check the chassis on your registration card before ordering to guarantee a perfect fit of the cap on the original reservoir. The thread pitch and diameter strictly follow those of the factory cap.\u003c\/p\u003e\n\u003ch3\u003eDoes this carbon cap really withstand engine heat?\u003c\/h3\u003e\n\u003cp\u003eThe concern is legitimate: poorly varnished carbon placed a few centimeters from a manifold turns white or clouds over in one season. Here, two elements answer the question. First, the material: a pre-preg cured under pressure retains its geometry where painted ABS warps. Next, the anti-UV polyurethane varnish, formulated for the engine environment, which withstands repeated hot-cold cycles and oil splashes without opacifying. In practice, a wipe with a microfiber cloth after each maintenance session is enough to preserve the depth of the \u003cstrong\u003egenuine carbon\u003c\/strong\u003e over time.\u003c\/p\u003e\n\u003ch3\u003eWhy order your BMW M3 G80 carbon cap from Becquet Voiture?\u003c\/h3\u003e\n\u003cp\u003eBecquet Voiture is a French specialist in \u003cstrong\u003eBMW M Performance accessories\u003c\/strong\u003e and only selects carbon parts tested in real conditions.
