8. Insert the long and angled metal tube into the hose and place it's extension/"arm" onto the bolt you just removed the nut from. Make sure you've got everything lined up the way you want it and then replace the nut to it's original position.

12. Insert large hose through the hole left behind by the stock air box. It will take a little forcing, but it does fit (snuggly) without any modifications.
 
 
   
How to Install the Injen CAI
on a 350Z

You will need:

  • Flathead Screwdriver
  • Phillipshead Screwdriver
  • 10 MM Socket wrench (and extension if you've got it)
  • A friend to hold air filter in place for you

1. Remove all plastic fasteners on the top of the front bumper and all the metal fasteners underneath which hold the brush guard (and the front diffuser if you've got the Track) to the bumper. You don't need to actually remove the bumper, you just need to be able to get your hands in there in front of the radiator to install the air filter.

2. Disconnect the negative battery terminal.

3. Remove the Mass Air Meter from the stock intake piping with a screwdriver. Make sure to set this aside on top of the engine cover where it won't get pulled down underneath something.

4. Begin to disassemble stock intake. I started by removing the air filter, the the air box (which takes a little prying because of it's position), and I worked my way up to the throttle body.

5. Install heat shield on exhaust manifold. This is where the socket wrench extension will help out a lot!

6. Prep the thinnest/shortest piece of hose by placing the smaller clamps on either side. Slide it onto the throttle body half way and tighten the top clamp.

7. Remove the nut on the intake manifold, just above the strut bar.

8. Insert the long and angled metal tube into the hose and place it's extension/"arm" onto the bolt you just removed the nut from. Make sure you've got everything lined up the way you want it and then replace the nut to it's original position.

9. Prep the second shortest piece of hose with the two larger clamps, and then fit it halfway on the metal piping. Tighten the top clamp.

10. Insert the black plastic piece for the Mass Air Meter into the remaining half of the hose. Position it so that the Mass Air Meter fits in with enough slack in its wires. Make sure the metal end is facing towards the front of the car.

11. Prep the large hose with the appropriate clamps.

12. Insert large hose through the hole left behind by the stock air box. It will take a little forcing, but it does fit (snuggly) without any modifications.

13. Fit hose around MAF and tighten the clamp.

14. Connect air filter to the remaining metal tubing and secure the clamp.

15. (This is where your friend can help a TON!) Get underneath the car, pull down the front diffuser (if applicable) and insert the metal piping into the hose. Position filter to desired place. And as the filter is held in place, reach through the top opening by the hood lock and tighten the final clamp securely.

16. Reinsert the Mass Air Meter and tighten the screws.

17. Replace all the fasteners for the front bumper (and don't forget to put the brush guard back on like I did the first time! lol).

18. Reconnect the battery and you should be good to go.

It took me and hubby about an hour and a half from start to finish and I also had him look over this write up to make sure I didn't forget anything, but hey, it's been a while since we did this.

You will need to reset everything inside your car--radio stations, clock, etc. since the battery was disconnected, but since you had it disconnected during the install, the ECU should adjust itself properly for the new intake with no problems.
