Polini Airbox Straight Air Filter - blue

Straight air filter Airbox in blue from manufacturer Polini.

If the engine misfires when opening the throttle fully or the carburetion becomes unstable with pressure changes, the problem is usually due to intake turbulence. The Polini Blue Air Box acts as a resonance chamber that stabilizes the air column before entering the venturi, improving crankcase filling so the engine revs higher and maintains power throughout the entire rev range.
