Best for my situation and area to replace
Would be five EXCEPT for the nut on the end isn't deep enough to make it easier to remove with metric socket. 1yr on 2004 ram 3500, w diesel hard area to get too, partially spun the nut with correct socket. Had to tap a 15/16th on spun nut to get it off.

Love this filter
This filter is fantastic hands down I dare you do your research contents on the inside or what matters I'll never buy another brand of filter for my diesel or my hemi. Miami 2016 ram 1500 is right now at 409,000 mi My diesel 6.7 Cummins is sitting at 219,000 mi this is all these engines have ever had on them this is all they were ever have. Well it'll be k&n oil filters and then it will be mobile one oil that's where I go and that's where I'm staying both quality products.

Great filter
My go-to oil filter. I have been using K&N for decades. I trust them. The endnut makes it easy to tighten/loosen. Threads are cut well and clean, oil seal does its job. Filtration is excellent, and will easily endure 15,000 oil chanve cycles using synthetic oils.

Great oil filter for a 6.7 litre Cummins. The nut at the bottom makes changing the oil filter easy
