Air Intake & Fuel Systems

Aftermarket air cleaners and fuel management systems are popular upgrades for Harley-Davidson Softail models. These modifications typically help improve performance, efficiency, and the overall riding experience. Aftermarket air cleaners are designed to improve airflow into the engine, which can increase horsepower and throttle response. Many aftermarket air cleaners feature superior filtration compared to stock units, which helps protect your engine from dirt and debris while still offering increased airflow. Popular brands include Arlen Ness, S&S Cycle, HorsePower Inc, and Feuling.

Fuel management systems are designed to optimize your bike's fuel-to-air ratio, especially after performance modifications (like an aftermarket air cleaner or exhaust). These systems allow your bike's engine to run more efficiently, ensuring it performs at its best. They are especially important if you’ve upgraded your engine, changed the air intake or exhaust system.

Riders often choose to use a Fuel Management system to better optimize throttle response, preventing lean or rich conditions that could affect overall engine performance as well as improve fuel economy while maintaining power. Some of the most popular brands that riders choose are Dynojet, TTS, and ThunderMax Tuner.

Upgrading both the air cleaner and the fuel management system together can make a significant improvement in an M8 Softail. The air cleaner allows for more air to flow into the engine, and the fuel management system ensures the engine gets the right amount of fuel to match that increased airflow. This combination can lead to noticeable improvements in overall performance, such as more power, better throttle response, and smoother riding.
