FAQ

How do I install a BMC replacement filter?

Open the airbox and replace the OEM filter — the two filters have roughly the same shape, so position the BMC filter the same way the original was installed.

How is a BMC filter regenerated?

Use original BMC kits only. Regenerate (wash + re-oil) every 20,000–25,000 km for best performance and service life; this varies with climate and terrain.
