Unleash the full potential of your Indian Motorcycle with factory-backed performance accessories. The key to making more power is increasing the amount of air and fuel flowing into the engine’s combustion chambers. Replacing your standard air intake with the Thunderstroke Stage 1 Forward Air Intake instantly boosts power and enhances acceleration. Plus, you’ll enjoy a deeper intake sound that perfectly complements the rich, throaty exhaust note of a Stage 1 Slip-On Exhaust Kit (sold separately).
In addition to increasing clean airflow into the engine, this high-flow air intake filter is optimized to help protect your engine from harmful dirt and debris. The Thunderstroke Stage 1 Forward Air Intake adds a sleek, distinctive edge to your bike—blending classic style with modern performance and putting a smile on your face every time you hit the throttle.
This complete air intake system kit includes a calibration card with a unique code to update your Engine Control Module (ECM) software from its standard setup. This software upgrade is required to ensure peak performance and must be installed by an authorized dealer.
