Yes I know another intake question. I can't decide between AFE, Fujita CAI, or Injen CAI. I'm planning on getting a blitz supercharger this upcomming summer/fall (2010) so I want to start building a good setup for the supercharger.

Are people really having issues with CAI sucking in water in the yaris?

It doesn't matter. Either of the three will do just fine and will give you the same kind of gain.

No. The filter on a CAI is usually located in front of the hard plastic tire shield, so water should not get into your filter at all, unless you drive through a 2' puddle of water.

AFE.... great intake i have it, more like a short ram with a heatshield, nice fit and finish, good quality piece, plus you don't have to worry about sucking up water

...which I believe is recommeded to be removed if running a S/C.

Read my mind Wee :wink:

The TRD's not recommended for use with s/c, there's a risk of some piece of that bypass valve being sucked into the blower... Noogie had to remove his trd cai, maybe Camell also? The one-piece designs dont present that problem.

I've heard the subject of hydrolock with a cai come up here before but never read any actual experiences.

like I said I have 3 that I like for price and performance. My whole thing is, what intake comes in contact with more cold air flow/ more air flow.

My custom modified airbox/snorkle/foglight cover, with K&N drop-in filter brings in more cold air than all three of these, guaranteed.

But anyway, definitely not the AFE since it's basically a short RAM with a heatshield.

That's what I was thinking... I was also mainly concerned about water getting into a cai... but I really doubt that now. I am also considering a blitz lm intake, it's about $150-$200

i'll tell you how i picked mine....and you should do the same.

find a good cheap used one with all the parts included.

the filters themselves are cheap if it's ruined, and the plastic doesnt go bad....and most bolts, threads, sleeves, mounts, or whatever else is involved can be easily repaired or replaced.

why pay 350 bux for a brand spankin new K&N when you can get one used for under a hundred....and most likely have absolutely no problems with it.

Exactly. That's wisdom + common sense speaking to you right there. :)

Are you disagreeing, and that you think it's ok to use the TRD CAI with the supercharger? A more clear answer, please.

I've had too many problems with TRD CAI. Its coming off as soon as I can afford something better. I'd go with the Injen.

what kinda problems have you been having with the TRD CAI? inquiring minds would like to know!

First the bypass filter broke. It cracked in half. Then, somehow, something arced to the lower intake tube and put a gouge in it. I have no idea what it was cause there was nothing electrical in that spot.

I didn't like the condition of the by-pass fitting on the used TRD I got, so I just swapped-in a plain coupler. Works great, no problems, and you can adjust the fit a little more by cutting the coupler to the length you want.

I haven't compared it to any others, but I'm really pleased with the performance of my TRD CAI (using a weapon R dry filter)
I can tell you that I am running 2-3 degrees above ambient, vs. 20-30 degrees above ambient with the stock airbox.

Does anyone from a colder climate have any thoughts about the CAI in cold weather? How cold is "too cold" for the engine to run efficiently?

From my experience while living in Missouri, a state that gets both extremes of temperatures, CAI's work best when the temperature is low AND the humidity is low.

Yup, I get that. Humidity impedes combustion. Have you run your CAI throughout the winter? Do you block airflow to it in any way during the very cold months, or just let it run as-is?

I have read on other threads here of cels. I mean its what $200 or $300 "well developed and tested" as others on this forum have stated "TRD" then it should not have these issues. The chepos are copies if you look at them with a cheap airfilter. Some people say the airfilters are shitty but mine has really been working well.

Yeah, I purchased a Bomz CAI from off eBay a month ago and it's a replica of the AEM CAI for the Yaris. It works like a charm and the filter that comes with is isn't bad at all. I just purchased a brand name filter to replace it even before the Bomz arrived, because I "assumed" that the filter would be garbage.

I actually sold the Bomz just a few hours ago to another gentleman on the forum. The only reason I sold it is because I wanted to hear my exhaust instead of my intake, which sounded quite aggressive. Some people like that. I do. But I like a mild, mellow grumble from the exhaust a lot more. :wink:
