The NOX Noise Filter 30mm Carbon/Chrome is a premium intake silencer designed to reduce induction noise on gearbox kart engines while maintaining consistent airflow and throttle response.

Featuring a 30mm inlet diameter, this NOX filter is commonly used on KZ and KZ2 engines, as well as other gearbox kart applications requiring a 30mm intake connection. Its internal noise-damping design helps meet circuit sound limits without restricting airflow or affecting engine performance.

Finished in a distinctive carbon fibre body with chrome end caps, this noise filter combines high-end aesthetics with durable construction. Lightweight and easy to fit, it is suitable for both race and test environments where effective noise control is required.
