Maintenance Note: Use only dedicated air filter cleaner and oil to preserve the 2026 integrity of the filter media. Safety Note: Because this system significantly increases oxygen intake, a **fuel management recalibration** (such as a Dynojet Power Vision) is mandatory to prevent lean conditions and ensure a secure, powerful 2026 ride.
