Frequently Asked Questions

Is the gasket pre-lubricated?

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

What makes the M-Pleat design better?

The zigzag pleat pattern creates more surface area for filtration, higher dust capacity, and lower pressure drop compared to standard pleats.

Can I install this by hand?

Yes — the fluted body is designed for easy hand grip. Most riders install it without tools, though a filter wrench works too.

How long does this filter last?

Full synthetic media resists aging longer than paper filters. Follow your bike's service interval for exact replacement timing.
