Swapping out your stock air cleaner for the Thunderstroke® High Flow Air Intake is a great way to ensure you have abundant air and fuel flow into the combustion chamber for extra power. By increasing airflow in and out of the combustion chamber, the V-Twin will see a boost in performance and improved acceleration. The air filter element is removable and washable to ensure consistent performance. The open-element design looks bold in either a chrome or black finish, and the 1” narrower design gives riders more legroom on the left side of the bike. Adding the final bit of style is the iconic Indian Motorcycle® script logo embossed across the face of the air intake.   Each kit is designated with a warning triangle to indicate the restrictions that may apply. Click on the link below to review potential regulatory penalties for inappropriate installations of this item.
