I am creating this Thread along with my Snorkel Install Thread with pics and videos along with step-by-step instructions for those of you that want to attempt these yourself. I completed both installs by myself. I recommend getting help from a friend if possible. It's nice to have company and an extra set of hands when needed, but not necessary.

This is designed for the 2010+ Toyota FJ Cruiser / 4Runner.

I installed this on my 2014 FJ 6MT. Toyota does NOT have this listed as a Prat for the 2014 Models, and will NOT install it on your 2014 FJ.

The TRD CAI fits!!!

It did throw a MAF Sensor Trouble Code after about 100 miles. Took it to Toyota and they Reset the code and everything has run fine for 500+ miles. The mechanic told me this was a common problem with ALL of the CAI's on Toyota's but nobody talks about it. Typically once the computer has time to learn the new flow rates, everything is fine.

Here is the Toyota Racing Development Cold Air Intake
Part Number: PTR03-89100

In this pic you can see the following:

Upper Air Box
Lower Air Box
Hump Coupler (Big, Red)
Throttle Body Coupler (Small, Red)
Air Inlet Tube
Air Flow Accelerator
TRD Air Filter P/N:pTR43-00083 (in box)
Literature Bag
Hardware Bag

8. Unwrap the electrical tape from the MAF sensor wire harness and remove any plastic clips within the harness,

Be careful NOT to damage any of the wires inside of the wire harness. You do NOT need any tools to do this.

10. Once you have the MAF sensor wires separated to the main wire loom, use electrical tape and create a perpendicular 90 degree angle from the main loom creating a "T" and use the supplied wire loom to contain the MAF sensor wires. Wrap ends with electrical tape as seen in the pic.

D. Install TRD Cold Air Intake

I Skipped steps 1-3 using the supplied zip ties, and waited until I had everything installed and went back and used my own zip ties to place the wires where I wanted them, out of the way.

4. Remove (3) rubber grommets and sleeves feom the OEM lower air box. To remove, first push out the sleeve, and then you can flex the rubber grommet to remove.
(Save these because you will re-use them in the next step)

5. Install the (3) OEM rubber grommets in the TRD lower air box. Then install the sleeves with a dead blow mallet. You can install the air box clips now, or wait until the lower air box is bolted to the fender wall so that you do not loose them.

OPTIONAL STEP:

If you are NOT mounting a Snorkel, you can skip this step.

If you are mounting a Snorkel to the TRD CAI, I recommend this step.

SEALING THE AIR BOX:
You can place a small amount of RTV Silicone around the air box drain to seal the air box. Place the rubber grommet and sleeve in place, and then just smear in enough silicone to seal it before mounting the lower air box to the fender.

Steps 6-11 I do NOT have pics of. The install was done at night, with intermittent rain, and I could not get any good pics.

You basically need to remove the bolts and clips from the inner fender well to Remove the air inlet duct and attach the Air Flow Accelerator, or the Snorkel Connector Hose, and replace the inner fender.

Unfortunately, this is probably the most difficult part (attempting to remove the plastic clips. I was told there is a "V" type screw driver available that will greatly assist in their removal. Each clip is about $4 at Toyota.

12. Insert the air flow accelerator into the air intake hole in the inner fender.

You can do this by squishing the air flow accelerator into the hole. It is very pliable. The TRD logo should be facing up because this is how it attaches to the air box.

SNORKEL INSTALL ONLY:
I purchased (2) 5" Stainless Hose Clamps, and cut of the Snorkel Connector Hose to fit INSIDE of the TRD Air Flow Accelerator Hose. I used one clamp to attach the hoses together inside of the inner fender, and the other clamp to attach the Air Lfow Accelerator to the TRD Lower Air Box (inside of the engine compartment. This MUST be completed BEFORE mounting the TRD Lower Air Box to the fender well.

Pic 1 is view from inside of the fender well of the TRD Air Flow Accelerator Hose. Place the 5" hose clamp BEFORE connecting the Snorkel Tubing.

Pic 2-3 are views of the TRD Air Flow Accelerator Hose from inside the engine compartment. You can see the Snorkel Connector Hose inside of the TRD Air Flow Accelerator Hose. Place the 2nd 5" hose clamp BEFORE mounting the TRD Lower Air Box to the fender well.
