Air filters

Well I found out wix doesn't make a 14x5 or 14x6 paper filter, nether does hastings.
I think I will just stick with the hastings af809 filter which is a 14x4 filter.
I imagine that is a big enough air filter for what I am doing, My engine is in a 4x4 truck, I'm not doing any quarter mile drag racing. But occasionally I do get into races up in the mountains with out of staters and out of towners.
For example this last hunting season, my wife was with me and I was looking at about 20 to 30 head of deer on top of this mountain with my spotting scope, I look over and there is a couple guys in a newer chevy looking at the same deer, I looked at my wife and said I think its going to be a race to the top of that mountain so hold on. And it was, but I beat them to the cattle guard and got in front of them, they got sick of my old dodge throwing rocks and dirt all over there pretty chevy and they backed off after awhile.
