Bill over at ASOG has gotten some nice looking fiberglass hoods in production. These are a different style than the usual Evo or Supra style hoods you usually see, but are purported to be actually effective at removing hot underhood air (unlike most aftermarket ones which are looks-only).

just a note about the fit... Bills car was in an accident previously and the body shop that fixed it did a poor job. The hood will align properly without a gap on a normal car.
