Looks like this is a good quality filter brand and I found a place that sells them for great prices.
Diesel-Filters(dot)com has the oil filters for $2.15 each and shipping for 10 of them was only about $10. The ML-1013 is the cross for the PF46 (smaller stock filter) and the ML-1010 is the cross for the PF61 (longer filter). I've decided that the longer filter really isn't much if any benefit so I'm going back to using the smaller one. One thing to note is for some reason the website tends to have the wrong item weights for a lot of the MANN filter items. I think someone entered the case weights instead of individual item weights. If you find this and contact them either through the website chat or on the phone they will fix it so the shipping doesn't come out crazy. The ML-1013 weight has been fixed since I ordered some, but I noticed the ML-1010 hasn't been fixed. Okay enough of a long winded post just to pass on what I thought was a good deal on some quality filters.
