Add some beautiful carbon details to your engine bay starting with your oil filler cap! Made from high-quality autoclave pressed dry carbon, this cap is not has a consistent beautiful weave, its highly durable and can stand the test of time! Dry carbon fiber is formed using a "pre-preg" or impregnated piece of carbon materials. This piece of carbon is first placed into a mold and then into a sealed vacuum (autoclave) to properly cure. This method creates the least amount of waste and forms a lighter version of carbon than the "wet" method. The autoclave vacuuming process of making dry carbon means fewer pinholes and virtually no air pockets in the carbon. Dry carbon is the highest-quality version of carbon fiber products that are produced. On top of that they coat this product in a UV resistant coating extending the life of this cap significantly! Don't wait and get yours today! You will not be disappointed by the fit and finish!
