❓ Quick FAQ

Which trucks/engines does this fit?
Cummins ISX15 and X15 15-liter engines used in major Class 8 semis — Freightliner Cascadia, Kenworth T680/T880, Peterbilt 579/389, Volvo VNL, Mack Anthem, and International LT/LoneStar.

How is NanoNet® better than legacy filters like the LF9080?
Unlike older cellulose/synthetic combo media, NanoNet® uses a consistent fiber web that captures 99.9% of particles without restricting oil flow, holding up under pressure fluctuations and preventing contaminant unloading during cold starts — ideal for extended-drain intervals.

How do I replace this filter?

1. Park on level ground, shut off the engine, and place a drain pan underneath.
2. Remove the old filter counterclockwise with a strap or cup wrench.
3. Clean the mounting surface and confirm the old gasket came off with the filter.
4. Pre-fill the new filter with fresh oil through the outer holes and lubricate the top seal.
5. Hand-thread the new filter on, then tighten an additional full turn after contact.
6. Top off the oil, start the engine, and check gauge pressure and the filter base for leaks.
