Fitment engine

PACCAR PX-9 diesel engines.

Why this fits: Fleetguard’s product page explicitly lists AF821M under equipment fitment for Peterbilt 320 with PX-9 engine (2017 and 2018). That is a direct engine fitment path for the PX-9 family, so the AF821M-to-PACCAR PX-9 relationship is supported. Verified against source ↗
