Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

BMW 4 Series G22 G23 Carbon Air Curtain Covers - Genuine BMW Pair
Elevate the nose of your 4 Series with factory carbon fibre air inlet surrounds that sharpen the look of the front bumper and complete the OEM Plus aesthetic. This left and right set replaces the standard outer vent pieces with real carbon fibre, finished in a deep, high-gloss clear coat for a premium motorsport vibe and seamless factory fit.
Designed by BMW for the G22 Coupe and G23 Convertible, these front bumper corner inserts slot straight into the existing mounting points. Expect perfect alignment, durable construction and a transformation that ties in beautifully with other factory aero pieces and Shadowline trims. We have installed these in-house and customer feedback on the fit, finish and overall visual upgrade has been outstanding.
