Well like the title says "I am new to this" I came from the diesel area. I just traded in my 2003 Ford F250 6.0 for a 2008 WRX Hatch. I got tired of spending the 600-700 bucks a month in fuel. Yes my commuter turned into my toy. The truck made 532 RWHP and 863 FTQ. I am looking to keep the car semi stock as of right now. The car has a cat back exhuast (brand unknown), AEM intake, lowered (Brand unknown), and rims. Any DIY upgrades would be appreciated and anything I should do as of preventative maintanance. Thank you a head of time.
