I never have done the napa air filter mod yet. I go through air filters like a mofo (live and drive lots on gravel) and didnt like the idea of it not being washable. I see riffraff diesel sells washable filters now so Ill have to order one up when I need to order parts. (dont know how familiar you guys are with diesels, but if you ever need parts, give Clay at riffraff diesel a shout, he is awesome to deal with and his prices + shipping are generally half price of what I can find up in Canada!)
I know ELC isnt absolutely necessary, but the trouble free operation and not having the hassle of having to test your coolant was worth it to me. Its more of an upgrade or modification, then an absolute necessity!
