Decided to throw a Champ Xl filter in the Rockauto cart last week with some other parts. It’s the 2835 filter, (or a Fram 3614, Motorcraft 910s equivalent). Interestingly, it’s quite a bit shorter than those. It’s only 3.11” in length, whereas every other 3614 equivalent I’ve seen has been 3.3-3.4”. I wonder why the Champ is so much shorter?
