Frequently Asked Questions

Will this increase horsepower on my Harley?

Yes — K&N guarantees a measurable horsepower increase by flowing more air into the engine than the stock air cleaner allows.

Is this street legal?

The system is not legal for California-registered motorcycles on pollution-controlled models. Verify your local and state emissions regulations before installation.

What's included in the box?

The complete intake system with K&N High-Flow filter, aluminum intake tube, throttle-body mounting plate, breather assembly, and all mounting hardware needed for installation.

Will I need to rejet or tune my carburetor?

Intake systems typically benefit from a fuel tuning or ECU adjustment for optimal gains. Consult a Harley dealer or tuner for your specific model.

Does installation require modifications to the bike?

No permanent modifications — the system bolts into the stock throttle body using the included billet mounting plate and hardware.
