Default Oil filter

I just received a Wix 51042XP oil filter for my 04 C-5. I was surprised at the physical size of the filter. It’s about the same size as my riding lawn mower filter. I was familiar with the larger SB Chevy filters. Any ideas why Chevy downsized their filters. My thinking is smaller size means less filtering media.

If you mean short, wait until you get down there. Same reason the oil pan is low and wide (seems I'm heading that way also ).

Even the 4.8, 5.3, 6.0, 6.2 engines use a very small short filter.
So apparently the engineers didn't see a need for such a large sized filter.
Stick with the Wix filters.. They are WAY Better than most..

To reinforce the previous post, I think it is the K&N filter that has a nut type of projection on the bottom of the filter. My car is lowered and when I tried that filter, at oil change time the nut was scraped and dented. Fortunately no further damage, could have been disastrous.

I have not got an answer to my question yet, but I Assume the reason Chevy went to the smaller filter was because of clearance issues.

Posts #2, 4, 5 and 6 all gave you the answer to your question; clearance.

it's also the same filter as the full-size trucks, but it works just fine. been using the Wix 51042 in both my vehicles forever (12yrs for truck & 8 for car) with no problems.
