Common questions
Is the air filter washable and reusable?
Yes, the high-capacity filter element is designed to be washed, re-oiled, and reused, offering long-term value and consistent performance for your Sportster.
What is the benefit of the Force Velocity Stack?
The patent-pending Force Velocity Stack accelerates incoming air, increasing its velocity and efficiency as it enters the engine, which can boost power and throttle response.
Does this intake require a fuel tuner for my Sportster?
While the intake alone may not strictly require a tuner, a fuel-air recalibration is recommended to maximize performance gains and ensure optimal fueling, especially if you plan other upgrades.
