This NAPA 9456 is a heavy‑duty cylindrical air filter designed for Kenworth truck applications.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It removes dust and debris from engine intake air, protecting your engine and ensuring proper performance. Over time the filter element loads with dirt, causing restricted airflow and power loss, so it should be serviced or replaced according to your maintenance schedule or when visibly dirty.
