The K&N Premium High-Flow Replacement Air Filter Set represents a pinnacle of automotive induction engineering, specifically developed to replace restrictive factory paper filters in elite high-performance vehicles. This premium kit is delivered as a matching 2-piece set to accommodate the dual air box configurations inherent to the high-output powertrains of BMW M-Power applications. Utilizing a signature multi-layered pleated cotton media treated with proprietary tacking oil, these filters are engineered to amplify clean airflow by up to 50% while sustaining an exceptional filtration efficiency rating exceeding 99%. This optimal aerodynamic relief enhances throttle dynamics, improves immediate acceleration, and sharpens net engine output under high-boost conditions. Built on ultimate sustainability, these reusable filters can be continuously washed, degreased, and re-oiled, completely operating for up to 75,000 miles under standard driving contexts before requiring an initial care service.

  • Locate both the driver-side and passenger-side air filter housings in the front portion of the engine bay.

  • Unfasten the external retaining clips or hex screws securing the factory airbox lids using the correct tool.

  • Lift the protective housing covers up and withdraw the spent disposable paper air filters.

  • Clean the inner housing cavities meticulously with a dry microfiber cloth to clear loose debris.

  • Insert the brand new K&N high-performance panel filters into place, ensuring the rubber sealing borders seat flush inside the structural tracks.

  • Lower the airbox lids back over the elements and firmly re-clamp the retaining hardware to prevent un-metered air bypass.
