The category is dominated by one name, with a couple of alternatives. Here are the best reusable oil filters for Harley-Davidson in 2026, best-first.

The picks, in detail
K&P Engineering Stainless Micronic Oil Filter (S4/S44/S69)

- Fits nearly all Harley models

- Black anodized canister
- Reusable stainless element
- Magnetic prefilter
- Stealth/custom appearance
- Same lifetime durability
- High flow
- Slight premium over machined finish
- Same high entry price
K&P Engineering Chrome Filter

- Reusable stainless micronic element
- Cooling fins + magnet
- Matches chrome builds
- Lifetime reusable
- Premium finish

Buying tips
- Confirm the exact size for your bike before buying — K&P’s S4, S44, and S69 cover all Harleys except the V-Rod; the S4 is the original 3-inch length.
- At each oil change, clean the stainless element with solvent/brake cleaner (or an ultrasonic cleaner) and wipe the magnet’s collected metal debris — that metal is a useful early warning of engine wear.
- A reusable filter costs more upfront but pays for itself over a few oil changes and eliminates buying (and trashing) paper filters for the life of the bike.
