RAM Air VS. Cold Air

[sidedown]

Hey, can you guys help me out. What is the differance between ram and cold air intakes. I know that cold air is more expensive, but thats about it. What one gives your car more power, makes it louder, or is there not really any differances.

-I would appreciate any feedback
Thanks for your time

Well the cold air intake (cai) goes under the engine and brings in cold air, hence the name. The short ram intake is up by the engine and brings in hotter air. The engine is better with cold air. So the cai will give you more power and better throttle response. That's why the cai is more expensive, because it works better. You get what you pay for basically. The short ram intakes don't do much at all for power, but it will change the sound of your exhaust.

the only problem you might have with the cold air intake is the possibility of the filter sucking in water. in order for that to happen the filter has to be completely submerged in water.

another thing to keep in mind is that short ram is sitting right next to the engine and may bring in hotter air than stock and may kill your performance

Yes, that's why the factory pulls air from outside the engine bay just like those super high-tech CAI's

Sssssssssssshhhhhhhhhhhhhhh! Dont tell everybody! The CAI suppliers will go out of business.

but unlike a cai the stock intake is usley ribbed (for her pleasure) and causes turbulance in the intake and thus less power.... hence the advantage of CAI or even Ram intakes :bandit:



Drive it like ya stole it !!!!

If you looked inside the stock piping, it's only ribbed on the outside. At least that's the way it was on the three different makes and models I've installed intake systems on.

Here's a link to the pictures of my CAI w/the bypass valve to eliminate the water induction into the engine.

i live in michigan and sometimes there can be flash flooding in my area, if i had a cai how deep would a puddle have to be for the intake to take in water? as deep as my car is off the ground? and is there any alternative positions you can place the intake where it would be less likely to suck up water? one last question, do those bypass valves defeat the purpose of having a cai because they limit airflow?

[jeef]

you have to have the intake completly submerged for it to matter... and yes the valve almost completly eliminates the purpose of the cai... its a very small gain as is...

the bypass valve actually is just another part of tube till you need it. it doesn't draw in air at anytime till it is needed. It has flaps and they are closed when the cai is working usually but when water is coming up the intake it sucks the bypass valve open stopping the water from flowing up more and allowing your engine to breath without death and honestly who cares about performance when you are ina puddle that is up to your intake?

i was asking if it limits performance in regular conditions, because having a valve there must create resistance of some kind, anyone know of an article or something that tests a cai w/ and w/o a bypass valve?

You dont need a bypass valve, just be smart and dont drive into a flooded road.

[DMC12]

You dont need a bypass valve, just cut a hole throught the top of your hood and point the CAI out the hood. That way you have a snorkel (to get respect from the 4X4 crowd) and you have ram-air (to get respect from the muscle crowd).

That is all.
