Installing a hood scoop(s) is good as it acts as a cool air inlet from outside to cool the hot air in the engine bay, esp good when the car is moving. Engine runs cooler, but I won't expect to have drastic improvement in engine performance, unless u know exactly how air movement from the front of the car, how air circulate and later how hot air being expel from the hood vent(s). Effective cooling requires both the SCOOP & VENT.
Just be careful when cutting out the steel panel when installing the scoop over the hood, preferably not altering the reinforcement "frame" under the hood.
