aftermarket HID kits will burn out your wiper motor, which is an expensive repair ($300-400)

the way the 2.0t engine works, blow off valves will actually decrease power (although they do sound cool)

as far as mods, a stage 1 engine tune is by far the best mod for our cars - most power for the least money. they will technically void your warranty, but i luckily found a dealer who just overlooks it.
