I think it's a pretty straightfoward install, but you can check this out if you need to.

should be easy--- I installed the K&N and took it out because it sounded like crap all in about an hour!
I am sure the TRD sounds/performs way better...

Where did you end up buying your trd cai from? I only ask because I'm not far from buying mine as well.netranger6 said:any points of interest to observe during install?
4 things I dealt with my TRD CAI:netranger6 said:any points of interest to observe during install?
- When installing the brass nipple insert into the tube, don't be alarmed if it does not thread in all the way. Just make sure you use teflon tape on it and tighten as much as possible without stripping. (brass is soft)
- I noticed the box started rattling a couple days after install. I checked all the mount points and they were all tight... still ratlled. Went to Home Depot and bought some 1" Rubber Foam Weatherstripping and lined the bottom edge of the box. Problem solved.
- Make sure you remember to disconnect your battery. Removed any chance of shorting the MAF sensor, as well as resets the ECU.
- One of the new bolts is a bit longer than the factory bolt it replaces... The hole it bolts into was not threaded all the way through for the longer bolt. If you have this problem, instead of forcing the new bolt through, remove the box, take the factory bolt and rachet it all the way in, then back out. (I cant remember which hole it was)
Did all that and install went well. Very easy, and very clean. Noticeable difference under load, and not ricey sounding in the leat. The bolt you refer to is the outer 12mm stock bolt on air box. It goes back in during install of TRD CAI. I resolved it by using another rubber grommet off of stock unit to increase space.pyst said:4 things I dealt with my TRD CAI:

To guy before this post, I bought it at toyotapartspeople.com, got it for $327 shipped. I am impressed by the quality of the kit, seems very thought out and executed.
goodstuff :thumbup: im planning on getting one soon 
does trd make a cai for the 4-cyl.?
[ I resolved it by using another rubber grommet off of stock unit to increase space.
Which rubber grommet are you referring? And that's not a bad price. Post some pics if you get the chance.

The install requires you to use the grommets off of the actual air box, with the metal inserts, for mounting new TRD filter housing. The right 12 mm bolt, as you're looking at it from front of truck, is too tall. So I used the rubber grommet, additionally, that was on the mounting point for the stock piece, where it attaches to fender well. Solved the space issue.R0dzilla7 said:[ I resolved it by using another rubber grommet off of stock unit to increase space.

:TRD CAI = installed
This past weekend I installed my TRD CAI. The original installation took me about 55 min. I then took it out for a much anticipated spin and was very dissapointed to find that the damn airbox vibrated so much I couldnt hear anything else! Honest, I couldnt make up mind as to whether or not I liked the sound of the CAI because the damn vibration was so loud. The problem is that its basically a box, but there are only three bolts to hold it down. Vibration is almost inevitable. To correct this, I did the following:
1. Disconnected the tube coupling from the airbox outlet
2. Removed the air filter
3. Removed airbox outlet by removing the three button head bolts
4. Removed the three bolts which secure airbox to wheel well
5. Under each of the three bolt holes, I placed a rubber grommet (from Lowes)
6. Secured three bolts - I repeated this step, in different sequence with respect to the three bolts, until I was happy with the movement (or, lack thereof). I found that it worked best to start with the washer and nut that attach to the double headed rubber thing (the hole closest to the radiator)
Problem solved. No more rattle, only air-sucking CAI goodness.
In the end, I really like the CAI. It has a great sound and really improved my throttle response. In 'passing mode' out on the highway, it responded quickly and effortlessly.
Installation time = 50min
Correcting installation = 45 min
