- This filter features DNA®’s Stage 2 kit eliminates the OEM intake snorkel of HONDA 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 R-H5N20-01 (sold separately) will increase the Airflow, Filtering Efficiency, Power, Torque and Throttle response.
- The airflow of this new DNA Stage 2 combined ALWAYS with the DNA Stage 1 Air Filter (R-H5N20-S2) is +75.22% more than the stock HONDA application! - Stock air box with DNA S2 & S1 air filter flow : 91.39 CFM (Cubic feet per minute) @1,5”H2O corrected @ 25degrees Celsius - Stock airbox with stock intake & stock air filter: 52.16 CFM (Cubic feet per minute) @1,5”H2O corrected @ 25degrees Celsius
- This DNA® Stage 2 kit is designed as a High Flow product for: ‘Road, off Road & Race use’.
- Fuel recalibration is suggested.
- 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.
