DYI:#1 To Install Joe-Z Intake on a IS300 01-05 [/B]
I just bought the car a month ago and this is my first Mod (when i told myself i wouldn't mod anything lol)
Figured i would post a DYI on my experience for future Newbie installs .
#1 Remove the Neg. on the battery , anytime you work around the engine bay this is a good idea. (also resets computer to recalculate for the mod 20mins off will do this)
#2 Next we need to remove that big black cover 4 bolts 10mm , easy just don't drop any of the bolts in the engine bay may take a bit of time to locate.
#3 Disconnect the vac hose at the rear of the intake tube . All you will need is your two fingers and slide off(I did this first , so when i got excited to pull old tube out i didn't yank it and cause other problems. )
#4 Grab your Phillips and loosen the clamps at each end of the intake tube for removal.
#5 Remove stock intake tube...
#6 Picture shows one of the benefits of upgrading to a Joe-Z intake . Inside of the intake tube and the resonator and this shows the non-direct flow of the stock intake tube ....Joe-Z is straight throw and free flowing .
(Stock intake tube)
#7 I now took the time to clean the Throttle body and MAF while i had everything apart , you don't have to but why not knock it all out . I just loosened the 5 bolts on the throttle body enough so i could spray both sides of the throttle body butterfly and used automotive rag to clean out . For the MAF i sprayed it out with a MAF/electronics cleaner ...
Throttle body was a little dirty...
Bolt back up all 5 bolt and TB now clean and is back on.(When bolting up with your other hand support the TB from moving , makes it easier...
#8 Install New Joe-Z intake tube (there are a couple ways of going about this is only one way .)
I started with TB side (used windex to help slide on)
#9 Then to make it super easy i removed the bolts holding the air-box to the fender wall for easy install of the bottom of the tube to air box..
#10 Tighten everything down (don't over do it)
#11 I then swapped my stock filter for a Blitz Performance filter (too add some extra flow)
Stock ------------------------------------------------------ Blitz
#12 Double check make sure everything is tight and where its suppose to be , then put your big black cover back on (don't over tighten bolts)
#13 Reinstall the Neg on the Battery (leave hood open )
Get in your car START it up (mine really didn't wanna start the first time Second time fired right up (results may vary) Now its going to run ruff for about 15-30 sec. mine was only about 10 sec.
Now just let it run for 5-10mins soo the computer can check up ....During this time make sure everything is tight (shut hood)
Now Enjoy the best bang for your buck!!!! I noticed 3k to 6k rpm the car is more spirited and very smooth ....

True Cold Air Intake ---------
LMS CAI Rare only true cold air intake made for the IS300 same as tube used in the LMS supercharger kits..Must buy used...$200.00
From what ive gathered.... back in the "day" LMS had a long true CAI for the IS300
if i recall correctly team Lexus had it on their racecar as well
also AEM makes a extension piece for their setups to mate up to the AEM SRI for the IS....
My version incorporates some piping i had laying around from my 240SX, and a OBX-r IS300 intake (pretty much the longer kin to Joe-Z pipe, with a maf adapter already welded)
its pretty straight forward including cutting the fender well opening...ALL PIPING IS 3 INCH
I cut my hole with a dremel cutting bit, and further smoothed the edges with a sanding drum...
the only thing that i have noticed that sets this apart from the LMS design is that it sits lower and my bends are more smooth. I run an Apex-i cone filter so its shorter than most filters and it sits about 2 inches away from the opening next to the foglight
the homework has been done here on my IS to acheive the best power for NA intakes and i beleive the happy medium was somewhere between 5-6ft total length from the intake valve to the filter, mine measures in at about a lil over 6ft...
with just the SRI the car felt about normal just way loud, with the longer setup its hard to tell because i did this the same time i did my header, so my outcome is skewed, spunky yes, low end well i toss that to the long runners moving my power band around, noise? not nearly as loud but it does sound pretty mean near the bumper.....
