Since i didn't see any guides for this i guess i'd make one since i installed mine today. The included instruction didn't have any pictures so for future reference...

Tools needed:
1. Philips and/or flat head screw drivers
2. Small socket wrench w/ 8mm and 10mm w/ extension

What's in the box:
Your plan jane gunmetal JoeZ intake ready for install.


Step 1: (Optional) Loosen and remove the negative terminal on your battery or remove the fuse for the ECU.

Step 2: Remove the large plastic engine cover. Just pull up on it and it pops right off.

Step 3. Remove the fasteners to remove the plastic cover by pressing down the middle of fastener. It should lock all the way down.

You should now have a stock bare engine bay


Step 4: With your screwdriver or 10mm socket wrench remove the top and bottom clamps. They will loosen but will not completely come off. Basically just loosen them enough so you can remove the tube. You will also need to remove the stock pcv vacuum line from the intake pipe by squeezing the little spring clamp. Remove only the vacuum line from the intake end only.


Step 5: With both hands remove the stock intake pipe by wiggling it back and forth from the air box and throttle body. The throttle body portion may require more elbow grease since it's sealed on pretty tight. Note: You do NOT need to touch any sensors on or around the air box. It will gently pop right off.


This is all you should have to remove.


Step 6: Now install the sleeve onto the throttle body first without the pipe being attached first with the clamp. DO NOT TIGHTEN THE CLAMP YET.

Step 7. Now put the pipe into the throttle body into the sleeve at a 90 degree angle.

Step 8. Now install the airbox portion with the second sleeve.


Step 9: Make sure neither end of the pipe is touching the throttle body or air box or you may have vibrations or chatter.

Step 10: Now that you have everything lined up tighten the clamps on each end of the sleeve. Make sure everything is nice and snug. DO NOT OVER TIGHTEN.

Step 11: Insert the end of the vacuum line over the new intake pipe nipple and squeeze the spring clamp back into place on the groove.

Step 12: Put the negative battery cable back if you removed it or put the fuses back in.

Step 13: Go start your car. It may stall on the first attempt and run rough for a couple seconds or minutes as the ECU relearns the new pattern. It is recommended to let it idle for about 5-10 minutes. Be sure all your accessories are OFF. (eg. radio, AC, etc.)

Step 14: Recheck your clamps are secure.

Step 15: Reinstall your engine cover by snapping it back into place. Reinstall your panel covers with the fasteners. The clips have to be "reset" in order for it to snap in again.

And enjoy your newly install JoeZ intake!

Notes: The car will need to relearn the Optimum Performance Levels so you will need to drive more or less 200 miles. This is normal and you will begin to feel performance gains in all ranges of RPM's.




Complete installation time: 15-20 minutes.
Enjoyment time: Priceless

Special Thanks to JoeZ and Luis @ Carson Lexus!

 

Nice, now lets hope people refer to this and dont make another 104083948234 threads on how to install a pipe. This can be cross referenced to the 3GS as well.

 

Woo!!! i jus recieved mine today.. installation was a piece of cake.. takes less than 10 mins.. sorta took me longer because i uninstalled the original tube and had to wait for UPS to drop the JoeZ off..

This should be added to the DIY section!!!!

 

+1... AMEN

 

Awesome post of the play by play install with photos... !!

Those Steps are very close in verabge to the install intructions..

But pictures are always better of course..

Thank You

Joe Z

P.S. - These steps can apply to the GS350 & GS450h as well........

 

yep it was based on the included paper instructions. I was just thinking hrmm this would be great if it had pictures with it.

 

Very Cool!!

Thank you again... for being patient...

 

Thanks for the write up! Im waiting for my Joez to come in today. ill definately be coming back to this soon

 

what happens if you dont remove the battery or fuse?

 

Thanks bro

 

The purpose of doing this is to reset your ECU so it can re-learn the airflow pattern for Optimum Performance Levels.

 

fantastic write-up.. that's all I can say

 

Thanks for the write-up as I will be soon getting the Joe-z pipe.

 

what's the difference between aftermarket intakes and the stock intakes? to a noob like me, i just see a tube haha. what's "inside" the tube?

 

Glad someone finally asked.....
