The stock one

stock was NGK Platinum- advances in mining made Iridium more available for mass use
It gives a little better all around than platinum- gen3 comes stock with Iridium
SO - NGK Iridium IX are used by many here 7 bucks each at parts stores
Usual reminder- seafoam the intake and gas a week before new plugs so they have a clean home to operate at 100%

adjusting the valves= do a seafoam gas and intake cleaning BEFORE valve adjustment
Crud is on the edges of the valves and will change its reading due to sealing
Clean them and it will set perfect
New plugs appreciate clean piston tops
Give it to the tech well cleaned and ready for new parts- get the most for your money

Traded in my
What about the laser iridium plugs? Don't really hear too much bout those? Is that because they're too expensive and ppl dont wanna buy them or are they inferior to the IX plugs?

The helms book says
For J32A1 Engine (non type-s)
NGK PZFR5F-11
Denso PKJ16CR-L11
For J32A2 Engine (type-s)
NGK PZFR6E-11
Denso PKJ20CR-M11
That is all I would use...
I just changed mine a few months back for the first time at 163K miles and the NGK's still looked like they had some like in them, I used the same ones cuz they lasted so long.
They prob would have went anouthr 50K no prob!

no they were going bad at 60k miles and will keep working long past that- but not at 100%
the book calls for NGK PLATINUM for gen2- gen3 comes stock with NGK Iridium
gen2 can use the newer better plug-
better metal = better spark and life
Laser refers to how the metals are welded together
We already have the hi tech plugs -dont need the laser weld

other plug styles have their place in other vehicles~
The TL with its hi-energy coil on plug ignition,, needs a super fine single wire plug
Test by ziners show denso cost more and wear out in 30 while NGK last a good 60,,
and will run to 100 for the foolish

Quick question it might sound stupid but do the IX have to be gapped, I tryed to make the gap smaller wit the tool but it doesn't seem to move, it says they r .044, an our manuels say .040.

You will most likely break the fine tip and you'll need to buy a new one to replace it. Just install them and call it a day. They will work fine.

k, i was using the six sided type one not those stupid round ones by the cash register

do LOOK at the plugs to be sure none have somehow been damaged during shipping- all the gaps should look equal
it has occured that one or 2 plug gaps were way off- thats out of millions sold so---

well actually its stock brand, and the newer better metal- NGK Iridium
platinum was stock and can be used
but if you can upgrade -why not!
the kragen guys on the left coast are wearing green Orielly shirts now,
and all the store brand products are changed over to Oreilly

Just bought my spark plugs from autozone, and bought the stuff i need to do the seafoam treatment. I guess they did have it haha

I'm guessing that they're not as popular because they cost more. The reason for the additional cost is the platinum disc on the ground electrode. Both the laser platinum and laser iridium use a platinum disc on the ground electrode. The iridium ix has a conventional ground electrode. Ngk considers both laser plugs to be 100k plugs, and the ix to be a 50k plug. They do consider the ix to be the "serious enthusiast's choice". I'm guessing most of the people on this forum fit that description in one way or another. Typically a car enthusiast might not let maintenance items go as long as the mfgr. recommends.

iirc its 13 ft lbs BUT check the box--it will also say an alternate method of finger tight plus x amount of further turn
If you have a torque wrench you can see what the current torque is before removal
A small piece of vac tubing is helpful in lowering the new plugs and starting them by hand
Use spark plug anti-sieze `sparingly` around 2-3 middle threads
Handle the coils like Moms best most expensive glass!!-
setting one down slightly hard can cause it damage internally and failure soon after
You DROP it... you bought it~

I don't have too much experience with this engine, but I will say that NGK plugs are some of the best made. I use them in everything. Iridium plugs are good for boosted applications and longivety. I have used them in my bike and it did run a little smoother. I have heard nothing but bad things about platinum plugs. That may just be dependant on brand like Bosch Plats are no good apparently.

just put in some new iridium ix plugs. rear passenger plug (don't know the number) was a pain in the butt to get to but other than that went smoothly enough. should i reset the ecu?

no need to reset the ecu on this job

the gen2 came with ngk Platinum, its just that with modern mining techniques- the cost of getting Iridium has dropped and made it available to the public
Before- race cars and airplanes used it in the plugs
