CTS Turbo N55 Cold Air Intake / Induction Kit for BMW 335i 335i

CTS Turbo Performance Intake System for BMW F3x N55 335i and 435i

Give your turbocharged straight six the airflow it deserves. The CTS Turbo performance intake transforms the driving feel of BMW F30, F31, F32, F33 and F36 models with the N55B30 engine, delivering crisper pedal response, a stronger spool-up and a purposeful induction soundtrack. On otherwise standard cars, typical peak gains are in the region of 10 to 15 bhp, with improved midrange punch and a sharper, more eager character.

Why this intake stands out

At the heart of this system is CTS Turbo’s cast aluminium hexagonal MAF housing. By matching the OE geometry, it maintains proper airflow measurement, so your DME sees clean, accurate data. The result is smooth idle, consistent fuelling, clean downshifts on ZF autos and excellent part-throttle manners, all while allowing the turbo to breathe more freely.
