Default Question About Air Intakes


I Know This Sounds Kind Of Remedial But I Had A Question.... What Is The Difference Between A Cold Air Intake And A Short Ram Air Intake? And What Is The Best Deal To Get? Thanks For Any Of Your Help

A short ram, or warm air intake (same thing) puts the intake filter generally in the same location as the stock air box, under the hood. A cold air intake puts the filter outside of the engine bay, generally inside the driver's side fender, where it can get colder air. Colder air is more dense, and contains more oxygen to burn.

*WARNING* Many e-bay and other sellers will call their warm air intakes cold air intakes. Don't be fooled. If there aren't 2 pipe sections, it's not a cold air.

A good warm air intake will give you like 2-4hp, while a good cold air will be around 10hp, in general.

yup, cold air is in the fender/bumper. Only thing with the cold airs is you have to stay out of puddles so you don't slurp up water.

BTW, they don't make cold air intakes for automatics (don't know if you have auto or manual). One can be home-made, though.

Ram air is usually referring to having the filter run to a hole in the hood.

A good WAI is good for making your car sound better.
A good CAI is good for making your car sound better, plus a handful of ponies if you're lucky.

Correct, but sellers tend to use "short ram" as the same thing as a warm air intake. Guess I'm just falling into using too much seller terminology, and not correct terms. *shrug*

A good WAI will make some hp, just not a lot (and most people think it does more than it does because of the sound it makes).

I still don't see how you can measure intake gains on a dyno...

you can't really measure it. It just gives you a more of an idea.

maybe if you had the dyno inside a wind tunnel?

Well, considering he's using a software dyno that measures while he drives down the road, it's being measured in a real world environment, not sitting in a building.
