Hi, I just bought a 04 WRX and winter is coming around the corner. I live in NY. So far on the list is rally armor flaps, and mabey snow tire if i can sell one of my other cars. Anything else i should get? Maintenance? Preperation? Anything for the turbo? What grade gas do i use in winter? Should I add an additive to prevent freezing? Any answers from winter-bound owners would be a great help. I've done alot of searching but havnt find alot. Thanks.
