Heard bad stuff about Fram (stuff like how the insides are sealed cardboard to metal and hot glue is used to hold stuff together - proven with pics). The Purolator oil filter was highly recommended - cheap as the Fram, but equal filtration to the Mobil 1 filter at a fraction of the price.
You'll notice that some part numbers will get you a shorter style filter, while some will get you a longer style filter. Both will screw on. I found the longer filter by looking for a large 2.8 FWD car of the same vintage as the Fiero. Im not actually sure that the filtration area is increased, but it can't hurt.
