This new Stage 2 Air Filter features DNA®’s advanced FCd (Full Contour design) and designed to work exclusively with the DNA stock replacement air filter. Correctly used it will increase the airflow, torque andpower of the engine.
Installation info are included with this new DNA Stage 2 Air Filter.Fuel injection recalibration is suggested but NOT necessary.
The filtering efficiency of the assembly with the DNA Stage 1 Air Filter (P-KT3N18-0R) is extremely high at 98-99% filtering efficiency (ISO 5011).
The airflow of this new DNA Stage2 Air Filter (P-KT3N20-S2) combined ALWAYS with the DNA Stage 1 Air Filter (P-KT3N18-0R) is +95.99% over the KTM / HUSQVARNA stock application!
Stock air box with DNA S1 & S2 air filter flow: 73.30 CFM(Cubic feet per minute) @1.5” H2O corrected @ 25 degrees Celsius.
Stock air box with KTM/HUSQVARNA stock paper filter air flow: 37.40CFM (Cubic feet per minute) @1,5” H2O corrected @ 25degrees Celsius.
This DNA® Stage2 Air Filter is designed for:‘Road, Off Road & Race use'.

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.
