Complete Your Intake Upgrade
This air cleaner kit includes the backplate, filter, and cover, providing a solid foundation for your intake upgrade.

For optimal results, consider a professional dyno tune after installation to dial in your engine's performance.

Common questions
What's included with this air cleaner kit?
This kit includes the round air cleaner body, backplate, a high-flow filter element, a mesh filter cover, and a billet end cap. A model-specific mounting bracket and breather kit are sold separately and are required for installation.
Will this air cleaner require a tune?
Upgrading to a high-flow air cleaner can alter your engine's air-fuel mixture. To ensure peak performance, prevent potential engine issues, and maximize your investment, a dyno tune is highly recommended after installation.
Is this a direct bolt-on replacement for my factory air cleaner?
The air cleaner itself is designed to fit, but it requires a separate model-specific air cleaner support bracket and breather kit for proper installation on your V-twin. Please confirm fitment for your exact year and model using our Shop by Bike tool.
