Step Four: Cut Intakes

OK. You’ve got two intakes. Both of them have a long section with an almost 90 degree curve at one end. You’re going to have to cut the curve off of one, so you’ll have enough straight pipe to run it to the headlight hole. Measure off 9 ¾ inches of the pipe, and mark it with a sharpie. You’ll only need this much pipe to run it out the headlight hole. Now, lay the pipe down, clamp it, and use your circular saw to cut the curve off. (Save that curve though, I used mine later on.) Make sure you dispose of all the metal shavings that you just put into the pipe. The last thing you want is metal shavings in your injectors! Now put the joint on the tubes, and use two hose clamps to secure them. Then put your reducer on the curved end, and use a hose clamp to attach it. Next, put your filter on the other end and use a hose clamp to secure it also. Finally you can lay that bad boy on there and get and idea of what it will look like.

Step Five: Remove Air Box

There are four snap clips that attach the top of the air box to the bottom. If you’ve replaced an air filter before you already know what I’m talking about. Undo the snaps, and then loosen the C-clamp that holds the air hose to the throttlebody. Now the top half should come off. Next, unhook the O2 sensor that sits on the bottom half of the air box on the side closest to the firewall. Just pull straight out and it should slide out. Now remove the rubber grommet that held the sensor in, because you’ll need it later. Next, remove the air filter and take a good look inside the air box. There are two or three 10mm long bolts that hold the bottom half of the air box to the frame. You’ll need an extension to take these off. Now the bottom half of the air box should come out. Don’t lose your O2 sensor!

Step Six: O2 Grommet

You’ll also want to hack off the longer stem for the Honda O2 sensor. You’ll need a much bigger hole to fit the Toyota sensor. So go back to your circular saw, cut it off as close as you can to the rest of the tube, and then use your unibit to hollow it out. Take a close look at the grommet that you pulled out of the air box. You’ll need the hole in the intake a little bigger than the inner hole of the grommet. I suggest taking one level out of the intake, and then test fitting the grommet. Do this until it fits snugly.

Step Seven: Relocate Negative Ground Cable

Now that you’ve got the air box out of the way, you’ll need to relocate your ground cable to your battery. It should have been connected to the top of the core support, but since you’re moving the battery around, you’ll need to find a spot closer to the back of the car so your negative terminal will still reach. I used one of the boltholes that the air box used. Just use the same bolt that came out of the hole.
