DNA Performance Engine Air Filter Kit (450cc)

Upgrade your ride with real, measurable performance gains — no modifications required. The DNA® High-Performance Air Filter Kit is a direct drop-in replacement for your factory air box, delivering increased horsepower, sharper throttle response, and filtration that outperforms OEM paper filters.

Choose Stage 1 for a straightforward filter upgrade or go further with Stage 2 to replace the OEM intake plate for a dramatic airflow increase and a more aggressive intake sound — the two stages together deliver the biggest performance jump.
