One of the main limitations of the air intake systems in the a45/cla45/gla45 series is the 69mm factory inlet to the engine. To overcome this obstacle and enhance performance, the Evoperformance air filter and CNC adapter are the ideal solutions.

This kit replaces the original 66mm plastic intake with a 101mm billet aluminium adapter, which effectively eliminates the restriction in the system. Installing our kit has resulted in gains of over 14kw in performance improvements.
