CTS Turbo BMW F30 F32 F33 Intake Kit for N55 335i 335i xDrive 435i 435i xDrive
Unlock intake noise, throttle response and reliable performance with the CTS Turbo BMW F30 F32 F33 Intake Kit for N55 engines. This free-flowing cold air intake is engineered for the BMW 335i and 435i platform, including xDrive models, and is built around CTS Turbo’s proprietary hexagon MAF housing for accurate airflow metering and smooth drivability. Expect a sharper turbo spool, an aggressive induction sound and proven gains of 10 to 15 HP on otherwise stock cars.
Why choose the CTS Turbo N55 intake
Unlike many round MAF intakes that can skew readings on the N55, CTS Turbo casts its own OE-style hexagon MAF housing in aluminium. This matches the factory geometry so the DME receives correct airflow data, helping to maintain smooth idle, consistent fuelling, clean downshifts on ZF autos and proper part-throttle manners. The result is a performance intake that drives as well as stock yet breathes significantly better.
