The round air cleaner body, hi-flow filter element, mesh filter cover, billet end cap, and universal mounting hardware. Model-specific bracket sold separately.

Is this legal in California?

No — this air cleaner is not legal for use in California on pollution-controlled vehicles. Check your state and local emissions laws before installation.

Will I need a tuner with this air cleaner?
