The (often referred to in the context of Harley-Davidson V-Rod performance) is an intake modification where the lower half of the airbox housing is removed or modified to improve airflow. What It Does:
It is often paired with a "topless" mod (removing the top cover) to maximize intake volume, leading to potential HP gains. Bottomless mod
While it can increase peak power, removing the intake runners can affect laminar airflow, which might negatively impact low-end torque for street riding. The (often referred to in the context of
Because it significantly changes the air intake capacity, you likely need a remap or fuel tuner to ensure the engine doesn't run too lean. Helpful Considerations: Because it significantly changes the air intake capacity,
If you are asking about a specific type of V-Rod, are you looking to: Keep smooth low-end torque for daily riding? If you tell me your goal, I can offer more tailored advice.
Many riders prefer to use aftermarket airbox kits (like Motohooligan) which are designed to optimize airflow while providing a better seal than a DIY modification.
