Wow! all those mods will net you a whooping 0.000 HP and a lot of laughs when going down the road.
Should've saved your $40 and start a wheel fund, save up for some 15s or 16s even if they're used, they be better than some rice covers. Why would you bother putting an aftermarket exhaust and then putting ricey wheel covers?
Come on TMan1281, half the stuff you suggested is rice, painting the dash panels?

I agree with the system, and maybe painting the engine cover to something not bright looking though.. maybe black or gunmetal.
Plugs, NGK or Denso work best with japanese cars, as for wires.. stay away from Bosch, go with OEM Toyota stuff FTW!
