This filter features DNA®’s Stage 2 kit eliminates the OEM intake snorkel of CF Moto models and offers higher performance and better intake sound.
This Stage 2 kit is designed to replace the stock plastic air box intake. Combined with the P-CF45S23-01 (sold separately) will increase the Airflow, Filtering Efficiency, Power, Torque and Throttle response.
The airflow of this new DNA Stage 2 is +68.00% more than the OEM CF MOTO air box cover!
DNA S2 air flow : 166.40 CFM (Cubic feet per minute) @1,5”H2O corrected @ 25degrees Celsius.
OEM CF MOTO stock air box cover air flow : 99.00 CFM (Cubic feet per minute) @1,5”H2O corrected @ 25degrees Celsius.
This DNA® Stage 2 kit is designed as a High Flow product for: ‘Race use only’.
6. The DNA EVA (Ethylene Vinyl Acetate polymer) closed cell seals
7. The DNA FCd design technology
This very special cotton is designed by DNA's R&D engineers for High Performance filtering purposes. The basic media is a non woven surgical cotton gauze with a modified TEX & THREAD, with extremely high strength of break. This unique cotton media, actually is a "hairy hybrid" featuring extremely high air flow rates and excellent filtering efficiency that exceeds 98%.

DNA Air Filter Service Kit for Motorsport PN: DSK-3001Auto
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.
