Designed to elevate both power and rider comfort, the Thunderstroke Stage 1 High Flow Air Intake increases airflow into the combustion chambers—helping your engine breathe easier for stronger acceleration and a smoother, more responsive throttle feel. This high flow intake system features a sculpted open-element housing paired with a washable, high-flow filter that enhances intake efficiency while protecting the engine through long-term, reusable filtration. 

Engineered with a 1-inch narrower footprint than the stock intake, this system provides added legroom on the left side while maintaining a clean, factory-level fit. For riders seeking maximum gains in power, throttle response, and a deeper, more resonant exhaust note, it pairs seamlessly with a Stage 1 Slip-On Exhaust Kit (sold separately). Finished in your choice of Chrome or Black, the bold housing features the iconic Indian Motorcycle script logo—delivering a performance-forward look that complements your bike’s design. 

This complete kit includes the full air intake assembly, reusable filter, calibration card with a unique ECM update code, installation hardware, and instructions. Each kit is marked with a warning triangle to indicate any applicable regulatory restrictions. Dealer installation is required for ECM recalibration to ensure optimal performance.
