Why spend $270 on a make specific CAI when you can buy universal CAI tubing and save a ton of money? Is there something I'm missing here? 
Two mods, ISR, DeckPlate...![]()
This is just as effective. If you can call it that. It'll sound cool, as will a CAI. But neither will do much if anything for your power. You may even loose some low end grunt.
Well here is what I did.
Deckplate mod was already done by previous owner.
I replaced the stock intake with an AirRaid Kit and Dry Filter $159 in April this year (Amazon)
AIRAID® - Jr. Kit - 2002 Toyota 4Runner Air Intake
Amazon.com: Airaid 511-734 Direct Replacement Premium Dry Air Filter: Automotive
Then I replaced my stock muffler (had a small hole in it) with at first a Magnaflow which worked great, sounded fine, but sadly was literally designed to fail.
So 1 month later replaced that with a Borla 40665 Turbo XL. $169
Sounds a bit better, same or better flow and NOT designed to fail.
BTW not much point in bringing more air IN if it has no where to go, I think you need a different exhaust to take any advantage of the intake.

Was the best $328 I have spent on it, it is the only thing that has given me ANY better MPG which as far as I can tell so far (little early yet to get an exact number) I am getting about 1-2mpg better on highway and about 1mpg better city.
I figured on my cross country trip I saved approx $138 in fuel cost in 27 days (7770 miles) which almost paid for the intake and Filter in one month.
I am also definitely getting a bit more Ummph, may not be much but it is noticeable.
So I can personally recommend the above combo and the AirRaid filter is much better than the small K&N that was in it plus is no oil.
Way better then a "cai" that's not even a true cai because it is still getting the hot engine bay air.
does that air raid thingy come with fittings for those ports or do you have to buy them? looks cool."
I will start to monitor it. Havent had my Scanguage on intake temps since I bought my t4r.my intake temp is usually 3-5 deg warmer than the outside air, whats the temp of the air with stock intake vs deckplate.
Why run one at all?
