A quick update. I did the mod and then added a K&N air filter (adding this afterwards also made a difference). I'm not sure how this is going to affect my fuel consumption yet - the first tank with just the airbox mod was about the same as normal, maybe 0.2l/100 higher. It definitely goes better though! Would I do it again? Without any hesitation. It's made me wonder about the exhaust now...95 3.0 Camp Car, 150 V6 Daily Driver[SIZE=4]

Some very, very quick images Pt1
Guys, my Airbox is already modded so I didn't want to remove it again, but here's some photos with the box in situ.
Prado Airbox 0.jpg
Shows position of air intake vents in driver’s side wheel arch.

Yellow arrows indicate clamps (4X) to undo and hose clamp to loosen prior to removing the Airbox Lid. Don’t try and pull of the manifold inlet hose now, it will come off more easily when the lid is free.
(For information only, the red arrow indicates the position of the Tabs you’ll to press down with a screwdriver to prise the right angled cowl off AFTER you remove the Airbox Body from the engine bay. This so you can get at the fan.)

Close up of Tabs you’ll need to depress by sliding your screwdriver in here after you remove the Airbox Body.

Undo the bayonet fitting on the underside of the clip with long nose pliers. This will allow you to move the Airbox Lid out of the way without stressing the wire harness. Alternatively, unplug the connector.
Undo this bolt.
Move the Airbox Lid out of the way and undo the two bolts inside the Airbox Body at the base. The Airbox Body can now be lifted out.

On the air inlet pipe that goes inside the mudguard, depress those Tabs shown in Prado Airbox 2.jpg and remove the right angled cowl.
You’ll see this Fan inside the air inlet pipe. Place a screwdriver at the weld points and pop the Fan out.
Replace right angled cowl.

This shows the original configuration of the Outer tube (Red), Inner tube (Yellow), and Fan.
Use a Dremel or similar to cut along the Red lines and remove all of the Inner and Outer tubes.
Clean up any loose material and swarf.

Finished product. Replace in engine bay, install three bolts and reconnect wiring clip. Refit Airfilter and Airbox Lid.
Another mod I highly recommend is removing the Vanity Cover which traps heat around the intake manifolds. A cooler system means denser air is being sucked into the fuel enriched mixture.
The Vanity Cover does nothing but make the engine bay look pretty to the non-mechanical eye.
To remove, simple lift at front and pull towards you. It’s only mounted on rubber hinges.
