The TWIN AIR pre-oiled air filter (manufacturer's reference: 151128X) is designed for motocross bikes that require reliable filtration without compromising airflow. Ideal for demanding riders, it combines a multi-layer foam construction with specific manufacturing processes to optimise engine protection and throttle response.
- Double foam: a first airy layer traps dust and sand, while the second, denser layer stops fine particles while allowing airflow to pass through.
- Pre-oiled: factory treatment for immediate protection upon installation.
- Durable adhesive: adhesive developed by Twin Air to maintain layer cohesion and resist solvents and petrol.
- Optimised format: slightly more compact than the original to free up volume in the airbox and promote airflow.
- Breathable seal: maximised contact surface with the housing to ensure airtightness. The bonding between the envelopes prevents dust from settling between the layers.
Reference suitable for recent motocross models, including KAWASAKI KX 450 X (2026), KX 450 (2026), and KX 250 X (2026). A practical choice for those who want to easily maintain their airbox and ride confidently on trails or in competition.
