CAI, Short ram, drop in 2azfe? need V6 experience

[WJN333]

I know Injen makes the short ram intake for the 2azfe, 2.4 liter I4. But does anyone know if there were extension tubes made for this application? In a kit? Or is a K&N drop in my best bet?

[RichD978]

call RJ, check the f/s section for his thread on tokico/tein combo for his contacts

[WJN333]

I called RJ last week and spoke with him about the latest batch of CAI extensions. He siad they would not work with the I4.

[RichD978]

ouch... the last batch worked on both.. Find a member with a v6 that bought the last batch and if you can confirm that it worked on both, buy the latest batch and find a way to make a trade

They never officially worked with any I4 application. You need to adapt them to work witht eh 5SFE or the 2AZFE, since the tube was built for the 1MZ.

You need to get a connector hose. The one I needed for the 5SFE was a 8" long 15 degree bent hose...got it off ebay.

2AZ may be different. I know for a fact that this has been done, and that person posted here about his sucess. if you search for CAI 2AZ, you may find it.

Ok, I called talked with RJ again, and he told me that the new run of extension tubes will not work with the I4 application (changed the design). Specifically made for the v6 S/C solaras. He also informed me that the the short ram is all i needed cause the short ram with the extension would be too long and the shrot ram comes with a heat sheild, somehow cooling the air?. This confused me more cause i thought that getting cold air would be more beneficial than the short ram getting warm air from under the hood. Little help please. anyone know of someone here that has one i could pm directly or you could ask to take a look at this?

Theyve always been made for the V6. Why would he have to change anything if theyve always been made for the V6?

I4's injen comes with the heatsheild, V6 doesnt. But I dont think the heatshield does squat since the ambient air in the engine bay is still hot as hell...which is where the CAI comes in. Just incase you were wondering, CAI wont do much in a I4 application either.

I have a CAI on my 5S. Its on my cardomain. I dont know what he could have changed in the design to make it fit the V6s better since the first batch run fit the V6 nicely.

[WJN333]

It seems to me that the short ram is not worth the money, being that it draws hot air. If what im hearing is corrrect it seems either a drop in airfilter in the stock air box, or a full CAI sysem (which are difficult to aquire) are the best options.

and Jon11582 votes for the drop in

[Jon11582]

There is no full CAI for our car unless it is custom made. We just have short ram + extension.

K&N Drop in is most practical. CAI growls though.

I got my short ram for free, which is why i went the CAI route. If i had to pay for everything, I'd go drop in. Cheaper, alot less work, and my huge bent coupler hooking up my SR and CAE looks kind of ghettoish.

For an I4 application, you need to buy
1) Injen short ram - ~$150
2) Cold air extension = ~$100
3) Long Angled Coupler = ~$25
4) K&N filter for CAI = ~$70

Injen Filter that comes with the short ram will NOT FIT on the CAI because the CAI is made for the V6 application which has a wider pipe. I know someone said before it would fit, but there is no way in hell this thing was fitting.

So were talking about $350 total if you buy everything from scratch vs less than $100 for K&N Drop-in. And mechanics and potential buyers in the future wont give you a weird look when they pop your hood.

Everyone has their separate schools of though on the matter. Here are a few facts so it'll help you reconsider your stance or further prove your point(s).

OEM: Designed with the *best* intentions in mind for fuel economy, smog regulation and environmental responsibility (easy to recycle/reusable/etc).

SRT: Short Ram Intakes is the type most people slap on because it's readily available for just about any car (look on eBay... Home Depot piping = yay). The fact is that in most applications, it will have a significant gain in high end power, but loss of low end power. Unless you have a section of your engine blocked off so it's not as hot as the typical engine bay, you'll be sucking in hot air. Hot air isn't as dense as cold air, so less fuel is required... so you may also be running lean like a mofo x_X More reputable companies (injen/aem) do research so that cars don't run excessively lean "under normal conditions". Always be careful though.

SRT w/ CAI: Short Ram Intake with Cold Air Extension. Since the air you are taking in is from the outside world, it's cold (relative to SRT engine bay temps) so the air is more dense. The dense air causes more fuel to be delivered to the cylinders, causing a slightly rich (assuming the ECM/Fuel system can deliver the specified amount!!!) mixture and more power throughout the powerband. The bad part is that most CAI are low on the car... so you may suck in water during 'flood seasons'. Often, people remove the CAI during rainy seasons. It's not necessary everywhere, but it is mandatory in some places.

High-flow Drop-in replacements: Slightly better flow than OEM and easiest to install. The power increase is almost negligable, but you may feel it in extreme conditions (very cold days). You may see gas milage improve slightly because the slight increase in air flow allows a better combustion environment (turbulance) w/o getting excessive (as found in the SRT). It's enough for most people.

If you really need more intake volume (from forced induction) then you may want the CAI and fuel system upgrade. If you want some more high end but won't mind losing a little torque, then get a SRT (some SRTs don't lose low end... Solara one does FYI). If you just want your engine to make some sound (lol) get the drop-in.

Hopefully this helps a few of you decide which way to go. There is no right way, just a more economical decision based on information and other present upgrades.

haha man. . . good shlock-dock-wikki-wacki-dacki

Ok couple more details,

Drop in - May increase gas milage, little or no gains in power (easy cheap)

Short ram - Gas milage ?, More high end, less low end (Moderate price)

CAI - Gas milage ?, Across the band power improvement, may have problems in heavy weather, may have to improvise installation and parts. (most expensive)

Someone please let me know about the potential gas milage gains/losses, and if these power gains will be noticealbe on this application, and im all set.

I think the diff is negligable at highway speeds. Not sure about city. Power isnt really noticible on any of these applications, since its no more than 5% gain no matter what you do. Your butt dyno will feel it though, because they all snarl a bit more.

[Jackass-Jeff]

drop-in: same if not + or - 1 mpg

SRT: Depends on barometric pressure and temperatures of operation... usually a slight loss because you need to rev higher to receive the same output for stop/go driving. During highway, it may increase by 1 mpg

cai: -2 or more mpg due to the nature of the device

i can only vouch for the drop-in... you may want to wait for some replies from other guys that have had the SRT and CAI

[WJN333]

"Butt Dyno" LOL, I like that.

Thanks for the info all. Trying to make the best informed decision i can. Any V6 people can tell me what they experienced when they implimented any of these three mods in the areas of power and gas milage?
