Bypass Oil Filtration
Secondary filtration systems, mounts and elements for extended drain intervals.
What this is for
A bypass system filters a small slice of the oil flow very finely and returns it to the sump, so over an hour it polishes the whole charge to a level a full-flow filter cannot reach. On equipment billed by the hour it is a cost-per-hour decision, and it pairs with oil analysis rather than replacing it.
Check this before you order
This is an installed system, not a drop-in part. Confirm mounting, plumbing and fitment for your engine before ordering, and plan on oil analysis to set the interval.

No prices on this page — here is why
AMSOIL sets pricing and takes the order. As an Independent AMSOIL Dealer I do not publish their prices, so the number you see on the AMSOIL page is always the current one. If you buy more than once a year, look at Preferred Customer first — it changes what you pay on every order.
