(888) 312-8812 Login SignupThe Fleetguard Engine Air Filter uses an axial-seal primary design to control leakage around the element interface while handling the main intake dust load. That sealing approach matters at the first filtration stage because unfiltered bypass around the element would defeat the media itself. The Fleetguard AF4195 replaces AF27948 in Peterbilt heavy-duty truck applications. That predecessor relationship and primary-stage role give buyers a clear reason to distinguish it from secondary elements or unrelated air-cleaner cartridges.
