The PACCAR Engine Air Filter is built specifically for the current-generation Kenworth T680 and Peterbilt 579, the model years PACCAR redesigned starting in 2023. The PACCAR D37-1061 seats into that redesigned housing without trimming or spacers, keeping the intake seal seated where the housing expects it. Because those cabs use a revised intake housing, the filter element carries a different shape and seal point than the version fitted to earlier T680 and 579 trucks. Confirming the 2023-and-up cab before ordering keeps the element matched to the correct intake generation instead of the outgoing design.
