The Honda and Toyota OEM filters are shrink-wrapped, either partially or totally. I have been using Mobil-1 and Purolator lately, and it bothers me a bit that they're not . They're just in a cardboard box where dirt and dust can penetrate.
Are my concerns over-blown? Would I be safer to use the OEM filters?
