What kind of car do you have? Whats available depends on your car. It basically works by bringing in colder air which is denser which has more oxygen in it, giving more power. I just put one on my car but haven't had the chance to drive it yet. It claims 8-12 hp which I guess would be noticeable, but cant say for sure till i drive it.

15 hp

Chev claimed when they first put cowel induction on the 69 Camaro that it picked up 15 hp. That is complete with cold air box. The hood without the box will actually create a vacuum around the carb at high speeds causing you to lose HP.

15 Hp equals 15/100ths of a second in the quarter mile. You may feel that on your lawn tractor but your not going to feel it in a car.

You will get the equivilant hp gain by taking the spare tire out of the trunk. She feel more po'erful now?

Do like they did i the mid 60s and take out your high beams, if it is a quad light car, and run a hose from there to the air cleaner....instand ram air. You could also have a scoop under the bumper like the 442s.


I don't think that you will notice any forced air system until you reach a certain speed.

Even with the light replaced there is a chance it won't be true Ram air. You've got to consider the slipstream. Even the "ram" air hood on the SRT-10's isn't true ram air. It's just cold induction. Now the scoop on a 440 six pack was true ram air. That thing was monsterous. I think it started to show related gains at about 80 mph.


Any cold air intake will still benifit you by opening up the intake and flowing more air. A well engineered system will draw the air from a fender or the cowel so it's cold. So they make a great stepping stone mod. Back it up with a higher flowing carb or TB. Next step would be a better flowing intake manifold and exhaust. So by all means do it.

As for gains? It does depend on the engine and how restrictive the stock intake is, but the carb/TB is usually more restricting. When I put mine on I noticed the increased noise more. I could feel it pull a touch better in the upper RPM's, but it really didn't make that big of a difference until I ported out the Throttle body. I've ran it with CAI and stock intake with the ported TB and there is a distinct difference.

when you choose one look for a few things. It needs to pull air from a cold air source. The wheel wells make a good place or even under the headlights. If it's located near the exhaust manifolds, look for a heat shield. It should also have larger tubing that has smooth curves and transitions. The better ones are mandral bent aluminum.

btw what kind of engine is this going on?

I don't know about equivalent, unless the spare weighs 150 pounds.

Ram/cold air induction

When we look at the aero on a full body there is a high pressure area at the base of the windshield..air tends to pile up there at speed..so if you want a cold air source for induction try this..

at the base of the windshield there is a grille for heater air intake.(0n most cars) .tap into that thru the firewall and use some of the flex aluminum dryer duct (the good stuff) and pipe that source of air to your intake..

Presto ram air..and the car looks stock from the outside..Picks up maybe 5-15 HP which maybe can get a few hundreths of a sec..but then a lot of races are won by very little margin..soo every little bit helps..

Go ramairbox.com and you can get their pitch on the advantages and see what they have to offer. Basically more HP and better fuel economy. I have one of their units on my EFI 383 and would not have anything else. I have never seen less than 95F intake air on the hottest of days. Dig into my photo album and you may see a pic .
