But as has been stated on here and many other boards before if the Hoods were sealed to the airbox and the baffles removed you would still only gain about 3HP at 100+ mph.
As for the Air lid the restriction is the Oval part where the resonators are. Putting on an aftermarket Airlid will eliminate this turbulente area smoothing out the flow to the MAF and therefore make more power.
Gotcha. Still seems a bit weird that removing the baffles and sealing to the air box only adds 3HP at 100mph. Isn't that the concept of the cold Air Intake systems that supposedly add a lot more HP than that (ie- adding outside air vs hot air from the engine compartment)?
