Sports Air Filter

Here is the back of the filter box, if you can read Japanese let me know what it says!

Here's the TRD air filter out of the box, red with the TRD logo.

This is your target, the air box. There are two brass colored clamps holding the air box lid down. You can see one in this photo that I've flipped back.  The other is on the opposite end near the positive battery cable.

Follow the battery cable down and you can see the other brass colored clamp that I've flipped down.

Now this is the tricky part. You'll see two black plastic clips on the side of the air box facing the rear of the car.  I used a flat blade screwdriver to wedge the lid of the box towards the front of the car.  Once it clears these clips you can hinge the box up to expose the air filter as shown here.

Here are the two filters side by side.  After 2,000 miles my stock white filter was very clean. Note the lack of the "Toyota" emblem on the back of the car.

Simply slide the new filter into the air box.  You can see that I unhooked a hose from the air box lid. I found it easier to move around with this hose unclipped.  I, of course, reattached the hose when finished.

This is a close up of one of the two black plastic clips at the back of the box.  Make sure the lid of the box snaps into these clips firmly, otherwise, your lid isn't on all the way and you'll have air leaks and contaminants getting into your engine!  The clip on the left (this is the right clip in the photo) was the harder one to snap in.

Once you've snapped in the back plastic clamps, clamp the front brass colored clamps back in place and you are done!  Be sure and check for a good firm seating of the lid.  Something interesting I noted, try to follow the intake tube back to where air originally enters, it appears to disappear into the fender!
