This carbon fiber intake kit is specially designed for the BMW N55 engine and precisely matches the F chassis of F10, F12, 535I, and 640I models. It replaces the original plastic intake system in place. It addresses the common problems of the original plastic intake housing of the N55 engine, such as high-temperature deformation, air leakage, and severe heat loss. The carbon fiber structure provides effective heat insulation, preventing power loss caused by high-temperature intake. It significantly reduces intake resistance, increases intake flow, effectively improves the turbo lag and acceleration jolt issues of the N55 engine, and makes the throttle response more sensitive and the power output more powerful. It is compatible with both the original factory and advanced power tuning. With program upgrades, it can significantly tap into the power potential of the N55 engine. The high-flow water-washed filter is durable for a long time and solves the problems of low intake efficiency and easy overheating of the original factory intake system. It is an exclusive accessory for old cars that need renovation and power upgrade.
