Re: This is a functional hood scoop
But not on US 4Runners;just a bling item here in the states.
The Firebirds Ram Air isn't just a direct shot into the engine. It's actually kind of convuluted before it's gets to the throttle body.

Here's an old picture of my engine:

It would be much better if the hood scoop was facing the windshield. That way it would let hot raising air out of the engine compartment. It is pointless on to try to use it to let more air in as the grille & fan already do that.

Or an improved design of the cowl induction of the '70 Chevelle.
Really,there is minimal to gain by making the hoodscoop functional since a open scoop does let a lot of dirt,bugs and whatnot into the engine bay thus requiring more upkeep.
A dirty engine runs hotter so the gains would be negated by just having a hole in your hood w/o some sort of screen to help reduce large debris getting into the engine bay.

The functional scoops are called "Ram Air" and can act a bit like a supercharger at higher speeds, it pressurizes the intake charge slightly, making sure their is plenty of air coming into the engine. I have a Harwood Ram Air Hood on my 2000 Dodge Ram, which I plan to make a twin snorkel to a custom filter box which will feed pressurized air at speed to the throttle body. My setup will undoubtedly draw in some water during a heavy rain while driving at speed, but not enough to cause any problems. I've had the hood on the truck with just the ram air openings cut out for a couple years just allowing more fresh air to pass through the engine bay, but have not gotten around to building the snorkel and filter housing yet.
Here are both my Rams, front one is the 2000 with the Harwood Ram Air hood, the back one is my 96 with the Reflexxions Steel cowl hood.
Neither are truly functional as they come from the manufacturer.

The cowl induction on that car was bad-ass. What a great time period in the history of muscle cars (1964 to 1972)RonMAIDEN said:

The '70 Chevelle SS396 (and SS454) with the 'cowl induction' were indeed awesome cars, but Pontiac sure had a nice setup on the '73 and '74 455 'Super Duty' Firebirds. They were truly "the last of the breed" when it came to performance cars. I found it hard to believe they ran so well on low-lead pump gas.
:bash:
Anyway, some of us are old enough to remember a "Super Duty" as something besides a Ford pickup truck.

'74 was one of the era's last gasps for HP as Pontiac snuck the 455SD in with a whooping 370 but was only rated at 310hp. Torque was also at 390ft lbs.
By that year Mustangs became Pintoized and the Camaro was ushering in a new low for ponies under the hood so the Firebirds had something nice still to offer for another year.
Then came '75 and 16 second 1/4 miles.
