Elevate your dirt bike's performance with the O2 RUSH High Performance Air Filter, trusted by Australia's top race teams. This premium air filter delivers the ultimate in airflow and filtration through its innovative Saw-Tooth foam design, which provides double the surface area compared to standard filters for superior contaminant trapping and engine protection. Ideal for demanding off-road conditions, it ensures optimal air intake without compromising power output or durability. Crafted with precision, the filter features a single-stage CNC profile-cut Saw-Tooth foam that enhances efficiency by increasing surface area and capturing more particles. The 10-15mm foam thickness strikes the perfect balance between filtration and unrestricted airflow, while polyurethane grommets offer secure, leak-proof attachment. A 12mm ultra-soft foam seal creates a tight bond between the filter cage and air box, minimizing air bypass and maximizing filtered air delivery to the engine. All O2 RUSH filters are laser-cut for exact fitment, ensuring seamless installation without modifications. Flexible glue seams prevent cracking and brittleness over time, extending the filter's lifespan even in harsh riding environments. Independently tested on models like the KTM 450SX at 16°C using the Superflow 400, this filter demonstrates exceptional airflow and efficiency, making it a must-have for riders seeking peak engine health and performance. Compatible across KTM, Husqvarna, and Gas Gas platforms due to shared air box designs. Easy to clean and maintain—simply wash with filter cleaner, oil, and reinstall. Perfect for motocross, enduro, and trail riding. Upgrade today for reliable protection against dust, dirt, and debris while boosting throttle response and power.
