i have great experience with FUJITA CAI but i kinda want a change. i know friends who own different products and it really depend on me that i know but i just can't make up my mind. theres too many things i think of before i get any one of the products so i have a few questions hoping fellow owners can help me out.

FUJITA, INJEN, AEM, WEAPON-R, TRD ( i want CAI ONLY)

1. how does the horse power and torque gains different from one another within the RPM range? in other word i want dyno numbers

2. which is easier to install?

3. which one have a cleaner look?

4. which one sounds better? the difference in sounds like which one is the loudest one of the group and which is the quietest one of the group.

5. overall quality? the fitment, materials, bends, type of bends and polish

6. where can i get the best price? i've checked it out on ebay, prices is including shipping ( TRD CAI $316.99 ) ( FUJITA CAI $220.59 ) ( INJEN CAI $280.44 ) i haven't find anything on AEM and WEAPON-R not sure where i can get it also.

7. this is for the TRD CAI owners. can you take a picture of the 50 states legal certificate? and if it show on the CAI it self i would like to see a picture of that as well? try to get a really good close up too THANX alot for your help.

well thats it for now and i really appreciate all the info that i get from all you fellow XB2 owners. THANK YOU ALL so much in advance

i just want whats best for my baby

As with everything its all about personal choice. I went with the fujita based on price, fit and finish. I felt that it was the overall best value. The only advantage I could see in any other CAI would be in the TRD. I don't feel that you'll get hassled as much by the dealer when you take it in. The upside to the AEM and Fujita over the TRD is that they use an oil free filter.

Good luck!

1. except for the injen there are no real publicized dyno graphs

2. all things equal being that the bumper and battery are removed, they are about the same difficulty. the TRD does require a more clumsy air box though.

3. all of them replace the ugly stock air box so they all have a pretty clean look. the AEM and Weapon-R is the only one that goes through the space between the battery and the ECU rather than going over the battery like others. the fujitas do have the option for different powder coated colors like bronze and black as opposed to the polished of the others.

4. sound levels are determined by what resonates through the pipe. the TRD and Weapon-R are probably the quietest because the TRD has a proper air box to baffle some of the sound and i have heard the Weapon-R and its more civil sounding than their short ram

5. if youre afraid of scuffing up the polished pipes then i say get the fujita in black. as for quality they are all big names and they are top quality. ive only seen the Weapon-R prototype CAI so i am not sure of final product yet.

6. ptuning is a sponsor on this site and they have a coupon banner ad on the top of this page for 5% off. they have pretty good prices on AEM, Injen, Fujita. the TRD you can get from sparks, carson, or scionpartspeople for a good price.


for me i got the AEM cause while i worked for a shop i was responsible for the "noob" work (wheels tires intakes) and of all the different intakes that i installed the K&N and AEM intakes were the ones that looked like they were designed by someone that understands that real people work on their car.
for the xB the tucked the pipe between the battery and the ECU so that the battery can be taken out easily without having to dissasemble the intake..

thank you miktf1 for a great amount info. you have provided.

so do you think all CAI makes equal improvements? of course sum claim to produce more but overall form what you mention seems that i can't go wrong with any one of them.

do you know where i can find pic of all these CAI products installed to the XB2?

thanx again

here's a shot of the trd cai installed, and for the install you don't have to remove the front bumper, just some of the fasteners on the driver's wheel well. also is a pic of the included side scoop (although you can get them from a couple aftermarket grill sellers carriage works and the like...)

and a pic of the TRD CARB sticker

haha not all CAIs are alike. the TRD makes the least power of the bunch at a claimed 6HP. this is because there is a relatively restrictive air box. the other CAIs have open filters. i think that the AEM, Injen, Fujita make about the same power probably about 6-9HP seeing that they have similar diameter and length piping and filter differences wont be noticeable. the weapon-r is a toss up ive yet to see the final product.

i have the AEM and here is my thread:

I am running the Fujita intake. It does go through the area of the battery and the ECU. It is not hard to install either. If you are worried about scratching the tubing. Wrap it in blue tape first and then put it in. I have done that many times. You can also just put some rags around the area you are working on and go that route. I will have the fujita intake on the site here in the next couple days.

i've seen the pics for the injen but it wasn't clear saying does it go behind the battery ( fujita ) or is it like trd?

the Fujita and the AEM both go through the space between the battery and the ECU. i debated between the two when i bought my intake i and thought that the AEM made more sense because the rubber/silicone connector is in the stock air box location. that allows me to place a bypass valve there later on so i get some back-up protection when the rain comes along.

the injen and TRD both go over the rear corner of the battery by the positive terminal. though the positive terminal is kinda rarely used cause it is possible to find other ground points, its still kind of weird to have it cross over the battery.

lvbitwiz, do you mean that it touches the - terminal or does it sit on top of it?

The TRD does not touch the battery at all. It kind of hovers above it. No worries. Even if it did touch the negative terminal, I wouldn't see anything happening. Both sides of the metal tube part of the intake are insulated from the body via the silicone hoses.

Does anyone know what Intake has the bigger diameter pipeing out of all the intakes??

what intake do have at the moment?
do you feel a difference?

I'm kidding about the Injen. I'd imagine they'd all be about the same in diamater. But I could be wrong.

I currently have the TRD and I'm happy with it. I can't say I could say I felt an immediate change, but I really didn't. I don't really see my xB2 as a race car. I liked the fact that the TRD came with the cool little vent and openned up the engine bay a bit.

none of them touch the battery. just that they are in the general area over the battery. i just think that its a bad design to have it cross over the top of the battery. this blocks access to it if i need to remove it and it poses a clearance problem if i decide to go for a different battery.

There's more room there than you think with the TRD, the battery comes out quite easily without having to move the intake

i've seen the dyno for the injen cai but not sure is it real. does anyone have one installed then got a dyno on it?

see if you can get the previous issue of siphon. they did a how to on installing the AEM intake and did a dyno. i just glanced at those pages while at the muffler shop so i dont have any exact numbers.

after i got my RS5.0 last friday i've been running hard ever since and on top of that i placed an order from pttuning for the injen cai blk until i got a call from pttuning yesterday told me the cai is on back order so i'm willing to wait 2wks for it. then out of nowhere i got an email from pttuning that the item have been ship today. so i was wondering whats going on here thinking is it some kind of error, btw i checked my email around 11:30am. then here is the big surprise, i saw a fedex truck outside my door 11:40am and when the driver carry that big red injen box coming to me it felt like an early x-mas for me coz i was expecting it to be ship 2wks later. i quickly unopen the box and install it into my baby, it toke roughly 30min and i was so surprise how easy to install it WOW. right after i'm done took it out and do a few quick runs around my block and i am so amaze how much the car pull at full throttle now and it was LOUD but i love it.very loud during full throttle and quite during casual driving so i am very very satisfied w injen cai. sorry for making this sooo long but i thought this is a good story to tell. btw THANX to all who help supply these great info in order for me to make a good decision that i'll be happy with for all the years to come, THANX again i really appreciate all your help. I'll post some pixs once my battery finish charging for my camera.

I was on TRD Sparks and noticed they have an Injen intake that they say has a pre-turned maf sensor and a dyno graph showing a supposed increase of 9hp. Is this one different than the one Injen has had out all along or has it just always been like that? I was just curious if this one is worth purchasing.
