Product details.
The DNA Stage 2 Kit was developed to specifically optimize the stock intake system. It replaces the original plastic cover of the air filter box and removes the original intake snorkel, allowing the engine to breathe more freely. Combined with the matching DNA Stage 1 air filter (sold separately), airflow increases significantly. The result is sharper throttle response, smoother power delivery, and a sportier, more pronounced intake sound. Proven DNA filter technology continues to ensure reliable filtration. The Stage 2 Kit is precision-made and tuned to the stock airbox. It’s for riders looking for a noticeable performance boost and a more dynamic ride. The product is designed as a high-flow solution for street use. For optimal overall system performance, adjusting the fuel mapping may be beneficial. Note: Replacement air filters in an OEM-style design generally don’t require additional registration.
