Ok well it looks like I will give the 3330's a try once I bury this last set of 6097's.
Thanks!

Just looked at the ngk.com website to see more info about the 3330's, they have also been replaced by the 6282. However the 6282 is JIS height and heat range 7. So I guess it will work as well. Unlike the 4644 which is ISO height.

No, as once a signature starts to list every mod under the sun it's basically becomes search engine chaff. ;-)

Not sure why you have more of a problem with my oversighted comment than mkiiina stating incorrect technical information (ISO vs JIS) backed only by anecdotal data.

Ok so does anyone know if there is a V-Power copper that exists that matches the specs of the NGK 6282?
I have been looking on NGK's website, but so far, I guess the only copper plug that NGK makes that is JIS and heat range 7 is the 6282.
I am not sure if the V-Power copper really makes a difference, but figured if it was available, I would run that over the regular coppers.
Thanks!

Sorry to really beat a dead horse, but I hope this information becomes useful to someone, I know it has helped me quite a bit.

So after looking at some NGK reference guides, I found a good one here http://ngkaz.home.att.net/wsb/html/view.cgi-home.html-.html I noticed that the 6097's are also ISO height, which is what isnms stated but it took a while to sink in :3d_frown:.

So I guess that means that the only NGK option in a heat range 7 is the 6282's however it looks like Denso might have a "U-Groove" std. plug which has a part number Q22PR-U that would work for our cars. It cross references with the old 3330's or the new 6282's.

Has anyone ran any of Denso's coppers? Or this plug specifically? Am I reading the part numbers correctly? Any ideas?
Thanks!

K for ISO.

Just for future reference, please read a little before posting or by looking how long some one has been on the site before you call them out. He is a very good guy and is one of the people who modded their car way before most other people on this site.

Teedoff,

MVP and others run the 3330's in all of their race cars, they don't last that long if you get on it all the time. I usually change them out every time I change my oil or right before I go to the track. They last for about 10k miles depending on how you drive but most here know how I drive so I change them out more often.

Once again...post count and join date mean nothing. Sorry bud, I bought my first Supra in '96 and have been modding my cars and many others since day 1. I used to support the SOGI website and list if you happen to remember that...before this site, SF, or mkiv.com existed. ;-) Maybe I should add all of this to my sig...lol.

I was corrected already, you should have let it go rather than continue to fill the thread with crap.

Yeah, I figured I would pick up some 6282's and give them a run. I don't mind having to change them out every 5,000. Better for me to be forced to inspect them! :icon_bigg

Thanks for your replies!

I've said it before, I'll say it again. I'm running the Denso iridium's that were in the engine when I got it. (JDM engine). They looked fine when I did the swap, and ran great for about 50,000 miles before the BHG. After the rebuild, I checked the plugs, and after cleaning, and re-gapping them, they are in the engine now, again running fine. I would get the iridum's, if I were you.

Watch out for that 4644. It's ISO and you want JIS.
Check out JIS (2.086") vs. ISO (1.98") height here http://www.sparkplugs.com/glossary.asp?kw=JIS&manID=0&pt=1

NGK Sparkplugs
•OEM NGK Platinum plugs 5275, BCPR6EP-N-8, .032 JIS
•NGK Traditional spark plug 2330, BCPR6ES .032
•NGK Traditional spark plug 3330, BCPR7ES .032 COLDER
•NGK Iridium spark plug 5689, BCPR6EIX .032
•NGK Iridium spark plug 5690, BCPR7EIX .032 COLDER

Denso Spark Plugs. ;)

•OEM Denso Platinum plugs 3113, PQ20R-P8, .032" JIS
•Denso Traditional spark plug 3007, Q20PR-U .032"

•Denso Iridium spark plug 5302 IQ20 .032"
•Denso Iridium spark plug 5313 IQ22 .032" COLDER

It's comparing Apples to Oranges.

However, the Denso Iridium has a thinner electrode and from what i've noticed thats what newer toyota and lexus vehicles come with.

(while i'm on a roll.)

Autolite Spark Plugs.

•Autolite Traditional spark plug 5503 .032"
•Autolite Traditional spark plug 3922 .032" COLDER
•Autolite Racing spark plug AR3923 .032" Colder

Cheap and pretty much throw away plugs. ;)

Autolite Racing IMO seems to be a waste.

Toyota switched from using the JIS to the ISO plugs at the end of the 80's in most new models or engine updates.

The plugs are similar and have the same reach, but the height is different. Like was said, the 7M uses JIS (Denso "Q"), the 1JZ and 2JZ use ISO (Denso "K").

Interesting note for users of the VVT-i 2JZ coils on the 7M, these coils/wires are meant for ISO plugs.

It doesn't come up much, but yeah, I'd definitely recommend getting the correct plugs.

Some good info in, all P/N's in one thread.

A question, do you guys drive around on street with colder plugs? I've run them and the car didn't seem to have the same low end as stock range. I normally run stock range 2330's but was considering colder for the track (road course, not strip)
Are yall not seeing a difference with the colder plugs for street driving?

This past February I put a set of the ngk BCPR6EIX (5689) iridium in my car. I paid about 6.99 per plug plus shipping. With the head having to come off this month, I saw that they looked quite cruddy. The car did burn oil however (I believe it to be a combination of a leaky #3 valve cover gasket and bad valve stem seals). My car is my daily driver right now, and its mostly stock, so the further I can get on a set of plugs the better. I don't think I want to put coppers in, but I don't think I want to spend 50 bucks on plugs again either. I might try my luck with platinums.

Just out of curiosity, have any of you tried silver plugs? Silver is supposed to conduct electricity better than almost any other metal, but I really do not know if that equates into better spark.

Please correct me if i am wrong, just figured I would ask.
