Copertura scatola filtro DNA Stage 2 Royal Enfield Bullet 350 2023-26

DNA Stage 2 Air Box Cover for the Royal Enfield Bullet 350

Engineered to replace the restrictive OEM intake components and increase performance for your Bullet 350. Out on the roads, trails, and tracks, this upgrade transforms the bike’s breathing, sharpening throttle response and delivering noticeable gains in power and torque.

By removing the factory intake restriction and opening up the airbox, this Stage 2 Cover allows your engine to draw in more air with less resistance, creating a stronger, more responsive ride. When paired with the DNA Performance Air Filter (sold separately), the result is a more free-flowing intake system, tailored for demanding riding conditions.

For optimal performance, DNA recommend re-mapping your bike to accommodate change in air flow.
