With neodymium magnetic box lids, accessing the filters for maintenance is a breeze. The AMS Performance's air boxes also feature full intake ducts that draw in only cold air from the front grille, maximizing your engine's power potential.

Installation is a plug-and-play affair with no permanent modifications needed. You'll enjoy OEM-style fitment features for secure mounting, and the AMS Performance's CAD-designed air boxes guarantee optimal performance and fit.

Crafted from motorsport-grade, hand-laid carbon fiber, our air boxes are not only high-performance but also durable, with no worries about yellowing or fading over time. The dry media filter ensures easy cleaning and eliminates the need for oil.
