Toyota Corolla DIY

Got the ECM replaced, so it’s time to re-install the CAI. Install is pretty straightforward. Note: Fujita doesn’t make a CAI for the Corolla. This one is for the Matrix XR. Still fits the same. Just a little bit of modification near the end. We’ll get to it then. Well, here we go.

Tools needed:
Flat-Head Screwdriver
Phillips-Head Screwdriver
Ratchet (10 and 11mm deep sockets) or Combination Wrenches of the same size
12″ Extension Bar
Provided Hex Key

Install Time: A little under an hour, based on your knowledge of intake installation and familiarity with your engine bay.

Disconnect the terminals and remove the battery.

Remove the Engine Cover.

Remove the crankcase vent tube from intake tube and valve cover.

Unclip the Vacuum Switching Solenoid (VSS) from the intake tube, then loosen the screw and disconnect the bracket from the VSS.

Loosen the hose clamps from the Stock Intake.

Unclip the harness from the metal bracket. Also unplug the wiring harness from the MAF Sensor.

Unclip the upper portion of the air box and remove it and the filter.

loosen the 10mm bolts to remove the lower portion of the air box and remove it.

Loosen the 10mm bolt holding the air inlet.

Remove the plastic clip holding the air inlet and remove.

Time to remove the bumper. There are 3 screws on each side holding the bumper on.

Remove the grille screws and the 2 clips in the lower grille.

If you’ve followed along your car should look something like this:

Here’s the stock air box and accessories:

And the new one:

And the bumper:

Now the Intake Install:

Install the 2.50″ to 2.75″ reducer hose and the hose clamps onto the throttle body. Tighten the TB side clamp only. You will see why later.

Install the vibration mount onto the threaded hole on the shock tower.

Remove the MAF Sensor from the stock air box.

Place on new intake pipe with provided machine screws. Tighten with hex key.

Install the intake pipe to the TB and align the bracket to the vibration mount.

Install the VSS to the intake pipe with the Phillips screw.

Install the vacuum hose onto the valve cover and the intake pipe. Plug the harness into the MAF sensor.

Use some wire ties to secure the vacuum hose to the wiring harness.

Install the 2.75″ straight hose coupler and hose clamps to the end of the intake. Tighten the intake side only.

Install the 2d vibration mount to the bracket.

Here’s where the modification is. The Corolla doesn’t have a threaded hole on the bracket. So I found a 10mm nut and washer in the garage.

Install the 2d intake pipe from the bottom into the hose clamp on the primary intake.

You are gonna have to work the intake around the wires for the battery terminal a little. I coudn’t get the intake over them, so i put it under as much as I could. See why you shouldn’t have tightened the clamps and vibration bracket screws?

Align the bracket to the vibration mount and tighten.

Tighten the 1st vibration mount as well as the remaining hose clamps.

Install the filter.

That’s pretty much it.

Re-install the battery.

And the Engine Cover.

And Voila!!

Re-install the bumper.

Reset the ECU.
