NOX2 Intake Silencer (OK & OK-J) - Carbon/Chrome

The NOX2 air filter has been developed for high-performance applications and represents the ultimate expression of intake system technology for kart engines.

It has been designed to maximise engine performance through a greater supply of clean air, helping to improve engine efficiency and overall power.

The system comes complete with a high-efficiency air filter and intake trumpets specifically developed to optimise engine filling and airflow dynamics.

The front air intake of the airbox has been carefully sized to ensure an optimal supply of fresh air, significantly improving engine performance.

Filtration of particles larger than 10 µm (10 thousandths of a millimetre) has been identified as the best compromise between airflow and filtration efficiency.

The 10 µm filtration level effectively traps the impurities generated by the front brakes, generally between 15 and 30 µm in size, which are known to be particularly aggressive towards the engine's internal components.

The new lamellar barrier, positioned in the lower part of the filter, has been designed to modify the airflow and reduce turbulence inside the intake chamber.

The rubber sleeve connecting the carburettor to the intake silencer has been developed specifically for 30 mm carburettors.

The carburettor is positioned so that its air inlet remains fully enclosed within the intake silencer body.

The new intake trumpets feature an optimised Venturi profile to increase airflow efficiency and improve overall performance.

For use in wet conditions, even in heavy rain, a quick-release rain cover is available that helps maintain excellent performance.
