Description

  • This new "DNA Stage 2 Adventure Expedition Kit" replaces the stock BMW air filter and the "restricting" plastic frame..
  • Designed to "sit" lower than the stock filter, frees the 2 air flow passages that direct the cold air from the front of the bike to the filter. Smoothly directing the incoming air towards the lower air box, we eliminate restriction, turbulence and improving torque and power.
  • With an active filtering surface of 132.300 mm2 this "DNA Adventure Expedition Air Filter" has 80% larger filtering surface and 38.5% air flow, compared to the standard replacement air filter.
  • DNA S2 Adventure Expedition Kit flow: 181.40 CFM (Cubic feet per minute) @1,5"H2O corrected @ 25degrees Celsius.
  • Bmw stock air filter flow: 131.00 CFM (Cubic feet per minute) @1,5"H2O corrected @ 25degrees Celsius.
  • The increased filtering surface and air flow will significantly extent the service intervals of the filter allowing the user to travel longer before cleaning the filter.
  • Regardless the revolutionary new design the filtering efficiency remains very high at 98-99%, with 4 layers of DNA Cotton.
  • This DNA S2 application can be used for road and off road use.
  • Fuel recalibration is suggested.

    FAQs About DNA Filters

    The DNA Air Flow Tests

    For the air flow tests, we use the most advanced flow bench available today. The ROTRONICS FlowScan, is a totally computerized flow bench that measures:

    • Mass of the air
    • Flow of the air
    • Temperature of the air
    • Absolute air pressure
    • Differential air pressure
    • Speed of the air at various points (Pit ot tubes)
    • Absolute humidity of the air


    The complete procedure is automated and computer controlled, eliminating human errors.

    The DNA Dyno Tests

    For the Dyno Tests, we use the industry standard Dynojet chassis dyno equipped with eddy current load control, Dynojet 250LC. Our dyno cell is equipped with a variable flow air cooling system, designed to precisely simulate real world conditions.
