I really liked this comparison of the new WIX filters, still looks like a good filter for the money. I do believe though, there is different build quality involved now in there building. I was sure that the older filters used a coil spring instead of the leaf spring and the filtration on the cheaper filter seems different. The Filtration on the older XP also seems better than the new XP. Why has some of our reliable filters seem cheap now? I guess it's about money now and not about saving the engines from dirty oil deposits.
