Reading the various threads, your recommendations state to use eight (8) discs with a stock air cleaner and no airbox mods. Typically, everyone first changes the air filter to a freer flowing, washable type such as a K&N or Screaming Eagle, then pipes are installed.

In my case I installed the K&N filter, but have the stock airbox (no holes or modifications). I just installed the Fat Shots. What number of discs will be a good starting point, less than eight (<8) since I got the aftermarket aircleaner or will eight (8) be a good starting point?

I want to avoid getting a SERT or PC until I can get it under my wife's radar, if you know what I mean.
