I am new to the Oldsmobile industry but really love my 98. It is so smooth and quiet to drive. My question is what does adding a cold air intake make?

Do you mean what the point of adding one is, or what power increases you will see?

Yes to both questions. Does it increase horsepower, gas mileage, or what? What will I gain?

Do a search here using "CAI" as your keyword.

If you have any questions, post them here.

Thanks for the information. I think I have decided to wait on this. I like the quiet ride that my car provides.

doesn't do much, might get like a 5-10hp increase, but it'll sound raunchier with WOT.

That's why I think that I am going to stay stock. One of the things I liked about my car was the nice quiet, smooth ride.

Slim chance you would ever see a 5 HP gain.

I didn't think that there would be that much gain. That just seems improbable. I figured if it affected anything it would be gas mileage.

im new to the whole forum thing and i havent quiet figured out what WOT means could someone explain for me? also would it alter gas mileage?

I don't know what "WOT" is either. I heard that they might have an affect on gas mileage. Just checking though.

WOT = Wide Open Throttle...aka pressing the gas pedal all the way to the floor.

Thanks, now I got it.

Depends on whether or not you use a true "CAI". Most think a cone filter is the same thing. Not so...A little better air flow, but you are still taking heated air from under the hood.
However, you can fabricate a true "CAI", that takes cold air from outside the box, so to speak, the air is much denser and HP, and fuel mileage will increase, without the annoying noise. 5 HP? Who knows? No dyno results except SOP. (Seat Of Pants) I did it on my 94 Cutty by fabbing pvc and an intake duct from underneath the car. Cut a cute little hole in the lower air dam. Worked great. Cost about 30 bux worth of parts from Lowes, and about an hours labor. Depending on the amount of beer you drink!

WOT = Wide open throttle.


The theory is, that since cool air is denser (contains more oxygen) the comp will add more fuel to keep the mixture at optimum.

This would result in the driver using less pedal at a given speed, and there would be no mileage change.

At WOT, there would be a power increase, but it would be dependent on the difference in temperatures entering the intake manifold. Most of the time, in the real world, the power gain is not even measurable.
