In a 2x2 twill each strand passes over two and under two, which gives the diagonal pattern BMW use on their own M Performance and M carbon parts. Choosing 2x2 means aftermarket and factory carbon on the same car match.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I look after a carbon fibre part?\u003c\/strong\u003e\u003cbr\u003eTreat the lacquer like paint: wash with pH-neutral shampoo, avoid harsh solvents, and wax or seal it. UV is what ages carbon, so a protected finish lasts longer. Forge Automotive can apply paint protection film to any carbon part before fitting, which guards against stone chips and keeps the weave clear.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this the same quality as BMW Genuine M Performance carbon?\u003c\/strong\u003e\u003cbr\u003eThe ADRO diffuser uses the same 2x2 weave specification and gloss lacquer finish as BMW M Performance carbon parts. Visually indistinguishable - though it is an aftermarket component, not produced by BMW.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I install this at home?\u003c\/strong\u003e\u003cbr\u003eYes.
