I've got an AFE air filter system with the little round filter. I'd like to put a paper one in for dusty season on the farm. The AFE filter is 8" across and 8" long with a 2" long neck that clamps onto the 4" pipe. Where would guy find something like that? I tried the local farm store that sells baldwin filters, but they weren't much help. I'd put in the stock airbox, but I'm not sure that it would fit with my turbo kit, I guess I could make it fit, but that's work. Any ideas?
