This Carbon Fiber Caliber hood is designed to extract more hot air from you inner cooler and put more fresh air down by the turbo.  We have added a larger air inlet and designed the inner hood to extract the hot air.  We have also redesigned the extractor so that the air that passes over the opening will help pull the air out of the hood.  You can purchase the hood in carbon fiber, fiberglass and any combination you can think of.
