you most likely need a new coil pack (585.00 + install)

performance, get a greddy exhaust its the best sounding!

Any universal intake or nuspeed intake is good

there arent headers stock is good enough (vw did a good job with them)

suspension, weitec makes good coilovers but are $$$ any "cup kit" will do fine just make sure you get eibach or neuspeed sway bar in front if lowering more than 1" or you are going to break an axle..
