COLD AIR INTAKE F8X M3/M4/M2C

The Dinan high-flow carbon fiber cold air intake is designed to improve engine performance by allowing more cool outside air into the engine. It features proprietary injection-molded MAF housings that are larger than stock, and larger Dinan conical air filters. The system is sealed like a factory replacement to prevent hot air from the engine compartment from compromising its effectiveness. It also includes carbon fiber air box lids and intake ducts with raised Dinan logos, rubber hoses, mounting brackets, and hardware. This product is not legal for sale or use in California or states that have adopted California emissions standards on any pollution-controlled motor vehicles.
