This was my post from a previous thread. LOOK and you shall find.

Full length intakes add more hp on lower speeds than higher (right up to the VTEC operation point). Short air intake system added more hp on higher speeds (right on the VTEC operation point) on a Dyno Test (with the hood open) but lost power in the real world due to heat. A downside of short intakes is that it places the open-element filter in the engine compartment where it is forced to ingest a diet of hot air. General rule of thumb, power output is reduced by 1% for every 10 degree increase in air temperature. Colder air has more oxygen molecules.

A few interesting things to consider...

No matter how long the intake, the piping is still aluminum and it is still passing through hot piping, heating the air.

You say the air is moving too fast through the pipe for it to matter?
Quite true, as well as the fact that when you are moving, air flows quickly in and out of the engine bay before it has much of a chance to heat up.

Either way, power gains are negligible, I;d say save your money, but if you really want something as a first mod, go with the cheaper SRI...

woulnd't you reduce the risk of hydrolocking with a bypass valve on a CAI? i heard even without one you have to drive through like 8 inches of water to risk hydrolocking....if u're dumb enough to do that you deserve to get u're engine smoked...

I have a bypass valve on my CAI. This past few months it rained with a furry. Nothing like a foot deep or anything but it did rain hard. Hard enough to have my wipers at full blast and nothing happened to my engine. It would be good to know people's experiences with CAIs (Not I heard or read from so and so).

Get a K&N filter and call it a day.

Oh yeah, Short RAM is geared towards more low-end and CAI is geared towards high-end HP h:
However minimal those gains are...

Anyways, just get a K&N filter and call it a day h:

Not worth spending the extra money for 1 or 2 more HP. An AEM SRI is only like 85 bucks anyway.

i hate filter on a stick.. short ram and its sucking in hot engine bay air.. cai and you run the risk of hydro lock.. BOTH filters are also exposed to the eliments allowing them to get dirty faster.. a dirt covered filter is pretty useless.. the stock air box helps protect against that..
