Keeping with the recent Dinan intake tradition the carbon fiber cold air intake for the F8x M3/M4 is beyond reproach. This intake kit makes the under hood appearance of the newest M's a work of art that could be the focal point of any car show or enthusiasts collection. While beauty is definately a concern; efficiency and maximizing the potential of the stock intake design were the keys to development for the S55 intake.

Our sealed system delivers as much cold outside air as possible to the engine by way of less resistance and a straighter freer flowing design which comes with an optimized carbon fiber tube.his optimized design yields increased HP/TRQ throughout the power band and shows consistent gains over stage 1 when combined with the stage 2 DINANTRONICS Performance Tuner.
