I have done the PSM cold air mods to my truck and I purchased the Amsoil nanofilter drop-in to go into the airbox. I then saw that AEM made a replacement for the stock filter that was a dry-element filter so I bought one of those as a backup. I have been going between the two and I think the Amsoil flows more air. Can this be right? I don't get as much smoke when I have the Amsoil in and the turbo seems to spool a little faster. Anybody know which flows more?
