Seriously learn to drive it first. This car will reward you with more joy on a twisty road than you think 158 HP could. Just adding a throttle cam on it will make it feel more responsive. A chip will gain you a few ponies and doing the cam offset key trick is as cheap as you can get. Forget the racy looking cone air filters that do away with the factory cold air set up and suck up hot engine compartment air actually taking away horsepower.
