welcome Bro!
Yes, I'm constantly doing research. I'm afraid of the motor going so thats why I want the Crawford separator. Also, the guy at the dealer says he is ok with stage 1.Welcome to the world of subaru. Subaru's are different than many different other cars, so make sure you read as much information as possible before doing any mods to ensure you are doing the right mods for what you want.
As far as the Dealer okaying an AP, I would guess most dealers would say 'NO' because they could always use that to refuse warranty work since that can have an effect on anything associated with the engine.
