Yea a generic one would be fine (that's what i was running on this car prior to the engine swap) should get about 120bhp

As for headlights i hear nightbreakers are quite good, but if your'e able to xenons would be the best way to go or even the hella projectors healights with decent bulbs or HIDs

Wiper blades i picked up a generic set of aero blades for £7 for both front and rear and they do the job, but if you keeping the car for a while the Bosch ones would be a good investment as they do last a long time.
