Frequently Asked Questions

Will this filter fit my Harley or Indian?

This OE replacement fits most V-twin Harley and Indian models — verify fitment against your bike's original part number before ordering.

How long do these filters last?

Full synthetic media resists chemical breakdown, extending intervals beyond standard paper filters. Follow your bike's recommended oil change schedule.

Is the gasket pre-lubricated?

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

Can I hand-tighten this filter?

Yes. The fluted design allows easy hand removal or tool grip for hand-tight installation without over-torquing.

What makes M-Pleat design different?

The zigzag pleat pattern increases surface area for higher dust capacity and reduces pressure drop compared to standard pleats.
