❓ Quick FAQ

Which trucks/engines does this fit?
Cummins ISX15, QSX15, X15, ISL9, and ISC engines used in Class 8 semis (Freightliner, Kenworth, Peterbilt, Volvo, International) and off-highway industrial/construction machinery.

What makes StrataPore™ media effective?
Its multi-layer synthetic design strips out microscopic particles while providing industry-leading water-coalescing performance — binding tiny water droplets together so they settle out before reaching the injectors.

How do I replace this filter?

1. Drain the old filter canister into a catch pan; disconnect the WIF sensor if equipped.
2. Remove the old filter with a strap wrench.
3. Clean the mounting surface and transfer/replace the WIF sensor with a new O-ring if reused.
4. Pre-fill the new filter with diesel through the outer holes, lubricate the seal, then hand-tighten an additional 1/2–3/4 turn after contact.
5. Reconnect the WIF sensor wiring.
6. Cycle the ignition to RUN (without cranking) 3–5 times to prime the system, then start the engine and check for leaks.
