Considering a CAI. Is there an ambient outdoor temp when it really wouldn't help much? For example, in the upper midwest it is "cold" a large portion of the time. If the temp is < 50 degrees and I'm driving at a reasonable speed, you would think that the air temp under the hood would have to be pretty dang cool, anyway. Or is taking in "even colder" air with a CAI always worth it?
Thanks...

 

CAI works even better when its colder

thnk about nitrous, why is it so good it brings basically freezing air in, the colder the better

 

Plus you engnie gets pretty warm, even during 33 Degree Rain on the freeway. It makes it sound alot better as well. But I am only doing the CAI until a decent plastic snorkle comes out...

 

well since there is really no "cold air intake" for a Jeep period, the biggest benefit of a "open" intake setup is more air into the engine. The differences in temp from the stock setup to a K&N, airaid, AEM, etc. is little to none I would imagine, even if there is a metal wall betweeen them and the engine. The benefit of a open intake system will be beneficial to anyone in any climate theoretically (maybe different for anyone in the extreme north/south hemospheres but thats just getting to far into it.

I would not let the climate affect your purchase in other words. go for it!

 

Yes the biggest advantage to cold air intakes is the increased airflow in a more efficient package. And they do work quite well. As for the nitrous comment the cooling of the fuel air isn't the primary purpose. The nitrous oxide is a way to transport increased oxygen into the fuel air mix to support combustion. More oxygen means you can burn nore fuel, more fuel means more horsepower, more horspower means more fun. Woo Hoo

 

HUH?? A free clue, oxygen.

 

im not tryin to rain on anyones parade, but CAI are pretty pointless. The gain in HP is very minimal (1-4hp(Ive even seen engines lose power)) and actually most "CAI's" produce warmer air due to the metal tubing. If you really want to get one, atleast look for one that has non metal tubing and some kind of heat shield. But for the money you could buy something else way more worth it.

 

I didn't think it that the temp of the air was the most important factor... I thought that it the increased airflow is what helps more

 

Cool air has more oxygen, warm air accepts more fuel. It is a catch 22.

And yes, more air means bringing in more fuel hot or cold.

 

Ok, I think I have a much better understanding now...more air versus cooler air. More fuel, then, naturally implies less mpg, correct? If you only gain 1-4 hp, is the extra fuel used significant?
