Is there a major difference in the Cold Air Intake over the Short Air kits?

And Pros or Cons?

Thanks

Really? This question again?

CAI's suck up colder air further away from the engine and all the heat.
Short ram's suck up hotter air closer to the engine.

CAIs makes more power.
Short rams make more noise.

You'll hardly even notice the difference. Save your money, go short ram.

Yeah really....lol. Im a newbe on here so im still learning where this stuff is at.

thanks..

Heh, it's cool, we all start somewhere.

I have an Injen CAI, and it's awesome. I have the opportunity to run either a CAI or a SRI (The Injen can operate as either one), and I'd rather run a CAI. I think it looks better.

Check out the classified section of this board; there are some pretty good deals going on. I got mine for 50 bucks, lol.

No worries, just try searching before next time.

What brand were you looking at? I'd go with the Injen for it's quality but if you just want to make some noise.. Buy an ebay intake and slap on a brand name filter and you're good to go.

EDIT: And what Norman said, if you get the Injen you can set it up as a CAI or SRI.. This works for tc's though, I have no idea for xB's.

That's my problem...I don't know which one to get? Seems everybody says there are different from each one. I'm looking for a good one but not for a arm and a leg. Ill have to look at the Injen...seems to have good reviews

Ebay ones work just as well if you get a brand name filter.. Its just the quality that I wouldn't trust. If you don't mind taking a risk try that route. If you want quality, you can never go wrong with Injen haha.

Cold_air_intake info

Short_ram_air_intake info

rather than asking which one you should use, figure the reason why they are effective?

at a certain low temp gas will no longer atomize, causing a drop in fuel efficiency. but a boost in hp productivity due to the fact that cold air occupies less space with more molecules per ca-pita (squishes in tighter).

look up Thermodynamic_temperature this is a refference which explains why molecules create energy and heat due to the movement of molecules in any given mass.

this is one of the reasons the product n20 or nitrous oxide is such a successful item. it not only provides a major fuel boost because it "as in its title" is an oxidizing/combustion agent. but it also dramatically drops the intake temperature of the air around it causing the molecules to pack in around the n20 making it burn that much more effectively as if it were packing in high octane fuel and much more air like a turbo or supercharger without the byproducts of bad fuel efficiency of such setups. (but requires charging once fully expelled)

so back to the point. cold air intakes do many things that short rams when setup poorly do not. for one a short ram usually will require an isolation box to keep ambient engine temps from causing a loss in oxygen density.

a short ram wont require a bypass for the air (used to fight hydrolock, not to be confused with vaporlock) which is where usually ground water may be ingested by the intake causing internal malfunction from the introduction of a foreign substance such as water.

when water is rapidly compressed it can become supercooled explained in depth in this article http://www.sandia.gov/news/resources/releases.

but that is uncommon, more likely the by product of a "liquid being introduced" is hydraulic pressure which can blow pistons/rods and bend valvetrain components quite easily.

items such as this cai bypass valve are excellent items as the will open up when a vacuum of negative pressure (sucking) from water clogging the lower filter becomes far too great. http://www.autoanything.com/air-intakes/65A3167A0A0.aspx

there are items just as good for less money on ebay. mine was 12 dollars.

i personally like cold air intakes for the sound, and the fact that high end motor response is much better due to the "cold air" but you can effectively set up a short ram "but" sometimes the cost is prohibitive after you look at isolation boxes and accessories to make it do what a cold air intake fundamentally does in the first place.

hope it helps

theres no huge difference.......only downside of a SRI is that it will draw alot of heatsoak from the engine bay and will hurt some of your top end power 5500 rpm and up...a CAI is the same but will beenfit more on the top end cause its not sucking up warm or hot air but overall they do the samething...but theres like a million threads on this and you will get so many mixed reviews on this so its up to you..some even say a CAI doesnt do anything which is false so just do lots of research and i wil tell you most would go with CAI

Cold air.

Then get the TRD bumper vent and let that cooler outside air in.

The CAI are nice, but you always have that feeling you are going to suck up water in them, granted I think the xBs place the CAI higher up than the tC, but it is still a fear.
The SRI are easier to deal with and not much worry of sucking in water. Just make sure that you never remove you inner finder and plastics that protect the CAI from water.

uscg_stamant

Go CAI.......period! And I don't see how you would suck up water unless your slammed and go through a 2 foot deep pond.......the filter is blocked off by the bumper and underbody plastics

I have a Tenzo CAI that i just replaced the filter with a K&N. It works great and intake temps are only a couple degrees higher than ambient air.
SRIs that I have seen on the xB2s don't look good because they have hot air coming in. I built a SRI on my old Alero and when i switched it to a CAI it made a huge difference.
