I just went through this from the opposite direction....
I went down to Oreilley's to get a filter, and the one they gave me looked about HALF the size of what was on there! So I did a little checking, and here's my theory, based on what I've been able to decipher....
It seems there are actually two different filters listed for the car, because the 'truck' one was too large for the A/C models. Eventually, most of the parts-houses have standardized (it seems) to the smaller ones, because they fit either application. But some of the more specialty houses will likely still have both (or at least LIST them both).
Both filters use the same gasket / mating surface and threads. The question for the smart people is this: Does a 'larger' filter necessarily mean it's better? (I just brought-up "size-matters" in my 3rd post here....

)
I'm no Boy-Racer..... but if I can't take every on-ramp at TWICE the posted limit.... I'm a total failure!
