We have brand new DTM carbon fiber airboxes complete with intake snorkel and all mounting hardware. These systems, derived from racing, delete the AFM or MAF and are meant to run with Alpha-N style engine management. Alpha-N piggy back module or custom ECU, e.g. from Motec, DTA, MBE etc, sold seperately. Remove your intake restriction and increase your power and torque throughout the rev range. Very crisp throttle response. For further details, please contact me at the following email address:
