This Install Guide is intended to help with the installation of the Agency Power Cold Air Intake on the 2010-2019 Toyota 4Runner 4.0L V6 and 2010-2014 FJ Cruiser.

Remove the engine cover.

Disconnect the air sensor.

Unclip wiring harness from the intake.

Remove the one 10mm bolt located on the bracket between the intake and the engine. You can leave the bracket attached to the OEM Intake. 

Disconnect the vacuum hose and breather hose from the intake tube.

Loosen the clamp at the throttle body.

Unhook the 4 clips holding the air box lid in place.

Next Carefully remove the intake tube and air box lid. 

Remove the factory air filter.

With the air filter removed from the air box housing you can now access the 2 of the 12mm bolts that secure the lower portion of the air box tray to the vehicle. There is a third bolt located outside the airbox that you will need to unclip the wiring harness tie to gain access to. 

Next remove the lower air box tray from the vehicle. 

Remove the air sensor from the stock intake tube.

Before inserting the sensor add the rubber bushing to the tube. Clean the tube with the provided alcohol wipe. Then remove the paper backing and install the rubber bushing.

Re-install the air sensor and use the 2 provided socket head cap screw to secure. Do not over tighten hardware. 

On the factory air box tray remove the 2 rubber grommet bushings. To remove, push the metal sleeve out and then squeeze the bushing out of the hole as shown. 

Re-install the bushings and metal sleeves into the holes of new air box tray.

Install the provided stud and bushing into the hole closest to front of the vehicle. With the nut tighten the stud and bushing down. Then remove the nut and washer to be installed later.

Place the lower tray into position. Scoop will tuck into the factory hole. The hole without bushing closest to the front of the vehicle goes over the stud with bushing.

Align the holes on the bottom of the airbox to the scew holes on the vehicle. Re-install the factory 12mm bolts. Because of the rubber gasket on the intake vent port, it may be necessary to give the intake a bit of force to align the holes. Make sure the bolts are straight before tightening to avoid cross threading the hardware during this step.  Add the washer and nut to the stud and tighten.

Install the included NPT brass barb firing onto the intake tube and tighten until snug. Next place the included coupler onto the end of the intake tube at the throttle body. Feed the side of the intake tube without the coupler into the hole of the airbox and then place then slide the end with the coupler onto the throttle body.  

Tighten clamps on to secure the intake tube to the throttle body. 

 Next Follow the small vacumm hose that was disconnected during the removal of the OEM intake and follow it up to the fuel pressure regulator. Remove the hose from port on the fuel pressure regulator and replace with the extended vacuum hose that is included in the kit.  Secure lines with clamps. NOTE: These lines are only vacuum. No fuel is present. 

Reconnect the factory hose line and clamp.

Re-plug in the air sensor.

Place the new filter on the end of the new tube. Clamp should be on outside of the new air box. Push filter up against trim lock rubber gasket and tighten clamp. 

With air filter in place tighten all clamps and check connections. Install the air box lid by placing it on top of the lower intake tray.

Secure the lid with the 4 provided button head screws.

You have now installed the Agency Power Cold Air Intake.
