This is a special hood for Mazda Miata NA cars that have done the conversion to a bigger V8 or V6 motor. As you know, the bigger engine will not fit under the OEM hood so we created this hood for you. This hood has a cutout for headlights. We do have a version of this hood that has the air duct. Recommended for the street or racing/track purposes. Weight: 8 Lbs. Uses OEM hood arms but has no provisions for hood latch. Must use hood pins.
