I need to find some micron rating, flow specs and other such info on the AFE and the Baldwin/TYMAR. I haven't seen an AFE in person yet but in pictures it sure does look a lot smaller, kinda like the K&N cone type that I have seen and know doesn't filter good. If it is smaller and supposedly flows more air then how does it filter tighter? Either way $40 versus $400 is an easy decision for me as long as I know the engine will be protected at least as good.
