I have an I35 and wanted to try a different oil filter. I was using Pure One Purealator but decided to go with Mobil 1's higher flow and see if I noticed a difference. The Autozone computer said I needed M1-180. I put it on but it seemed like a very small filter compared to the Pure One and the OEM. Is M1-180 the right size of should I be changing my oil again?

 

I think you meant to say a Mobil 1 108. A larger filter that will work is the Mobil 1 105 (for the 3.5 only). It's what I use on my Max.

The Mobile 1 110 filter is also larger and will work on the 3.0 and the 3.5.
