Frequently Asked Questions

How does the M-Pleat design improve filtration?

The zigzag pleat pattern increases filter media surface area, allowing the filter to trap more contaminants and dust before requiring replacement.

What does the louvered baffle screen do?

It holds the media in place and creates a swirl pattern that forces more oil across the filter media, improving capture efficiency.

Is the gasket pre-lubricated?

Yes — the gasket comes pre-lubricated and sealed in shrink film to keep it clean until installation.

Will this fit my Harley or Indian motorcycle?

This is a V-twin filter compatible with most Harley-Davidson and Indian models. Verify the OE part number on your current filter or in your owner's manual to confirm fitment.

How often should I change it?

Follow your motorcycle's recommended service interval, typically every 1,000 to 5,000 miles depending on riding conditions and your owner's manual guidance.
