Frequently Asked Questions

Does this come with a mount kit?

No — you must purchase a separate mount kit to secure this air cleaner to your bike.

Will this fit my Milwaukee-Eight Harley?

Yes, but you need to order adapter spacers separately to accommodate the M8 mounting pattern.

What's the difference between the black and chrome finishes?

Both use the same CNC-machined design and velocity stack. Chrome offers a polished look; black anodized with contrast cut provides a darker, more aggressive appearance.

Do I need to retune my carb or fuel injection after installing this?

The air cleaner alone may not require remapping, but tuning is recommended to optimize fuel mixture for the improved airflow from the velocity stack.

Is this street legal?

This is an intake component for custom and show bikes. Verify local emissions rules before installation — some areas restrict aftermarket air cleaners.
