Key Features
- Enhanced Airflow Dynamics: Features an optimized 18-blade profile and angle design that increases the volume of cooling air delivered to the cylinder fins, effectively removing heat faster than standard fans.
- Overheating Protection: Specifically engineered to maintain engine thermal stability, preventing "heat fade" and power loss during extended full-throttle operation.
- Precision Balancing: The balanced turbine design reduces rotational vibration and noise levels, offering a smoother engine feel and protecting the crankshaft bearings.
- High-Temperature Resilience: Made from a durable white polymer that resists warping and brittleness caused by constant exposure to extreme engine heat.
- Seamless Installation: Designed to flawlessly dock with the original cooling fan holder, ensuring a simple bolt-on replacement process without any modifications.
