Air Filter vs CIA

**jazzitup** · April 26th, 2009 05:58 AM

Hi Guys, just a question what's the difference between an air filter and a CIA? If i am planning to have my headers and exhaust modified, would it be ok if i just use an air filter?

Cheers.

Sorry guys, it's CAI.

You mean a stock air box vs CAI.

CAI is also usually filtered, but the difference lies in where the air is coming from. CAI systems have inlet spouts that are positioned in a way that only cold air gets into it. Stock air boxes usually have the inlet spout inside the engine compartment, so it implies that it sucks in hot air.

It's a well-known fact that cool air from the outside has higher density than say, the hot air under the hood. That will translate to a slightly higher oxygen content for the engine.

i'd get a CAI if i could afford it. my hondas all run somewhat better when the air outside is cold or when it's rainy.

i'd mount mine with the intake near the headlights

*volts - how much did it cost you for the CAI?

What i wanted for my car is an air filter from k&N the cone shaped. I inquired on them how much would it cost to install the cone shaped filter, they told me it's around 18k for the kit.

I forgot to asked this question to them maybe some of you could help me. What does the kit include?

sorry guys newbie here.

Cheers.
