Will an fram 3980 oil filter work for 94 Chevy cavalier?

You need to check your owner's manual or a reliable online parts database (like AutoZone, Advance Auto Parts, or RockAuto) to be absolutely certain. While the FRAM 3980 is a common filter, its compatibility depends on the *exact* engine in your 1994 Chevy Cavalier. There were different engines offered that year.
