- 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 and power of the engine.
- Installation info are included with this new DNA Stage 2 Air Filter.
- The filtering efficiency* of the assembly with the DNA Stage 1 Air Filter ( P- KT3N24-01) is extremely high at 98 - 99% filtering efficiency (ISO 5011), with 4 layers of DNA® Cotton.
- DNA Filters are supplied pre-oiled from our factory. The correct amount of DNA oil is applied οn each filter individually.
- This DNA® Stage 2 air filter is designed as a High Flow Air Filter for: ‘Road, Off Road & Race use’.
- Fuel injection recalibration is suggested but NOT necessary.
*Filtering efficiency is the amount of “dirt” the filter can maintain (stop) and protect the engine efficiently. For example the DNA® Filter for every 100 grams of dirt that it will receive, it will hold 98-99 grams, this applies even to fine dirt as small as 5 microns.
- 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 (Pitot tubes),
- Absolute humidity of the air.
The complete procedure is automated and computer controlled, eliminating human errors.
