napa platinum 47620 on sale
These are on sale at napa for $8.04. I've ran one for about 3k so far and certainly haven't had any complaints about it. From what i understand it "should" be comparable to a donaldson or fleetguard filter, but not sure if up to the level of the stratopore media. But for half the price, i guess you can't expect it to be. It is reported to be a synthetic media thats wire backed. It's made by Wix (as are all of the napa filters from my understanding). Here's a discussion with pics of a smaller filter.
