Spark plug Gurus inside please
Would anyone run this plug on a nitrous application? Some lt1 guy is claiming it to be the lt1 nitrous plug.

Actually they are a very good choice for nitrous plugs. As Brad said, its the Iridium version of the famed TR-6. I went about .003" larger gap with them compared to the TR-6 plugs, doesn't sounds like much but in the grand scheme of things, it is a difference. More versatile, NA and Nitrous, than the copper based 6, burns clean.

What about the tiny electrode becoming a blow torch? Not much to dissapate heat, imo. Having any issues like detonation, high cyl temp, inadequate fuel octane, to much timing and other scenerios could cause this little electrode to become glowing red hot, no? Just because it has worked on certain cars with no issues, should we be claiming it's a good nitrous plug? Also, why do no nitrous manufacturers rec this plug over the standard NGK Tr6, see my point?

All I can say is it is a TR6 that is irridum, it is made to the same specs that the copper on is. If it is to the same specs that the copper TR6 is then it should work fine. The irridum may be stronger than copper thus allowing it to be smaller and still not break or anything. Maybe Ill try em out next plug change.

I understand what you are saying, my point is that the smaller irridium tip may be able to dissipate heat just as good as the larger copper tip. If that is the case then they are equal to each other, its all based upon the metallic properties of the 2 metals.

Because I like my engine The BIGGEST benifit of most of the plugs they keep coming out with is you do not have to change them as often. Well anyone running juice needs to pull their head out of there *** and check their plugs on a regular basis. Plugs are a consumable item IMHO. If there is a problem a good plug will consume itself before hurting the engine. That is why Copper is a good plug material. The harder the material the more Damage it will do on the way out.
I myself won't spend extra money to be able to Flaunt a name part
I will run a good racing plug and be happy with what my Sig has to offer

Actually it makes it worse

One more thing to point out on this plug, it's a projected tip plug, again not ideal for nitrous use. Go to NGK and you see that there rec plugs for nitrous do not have irdium electrode tips, nor do they have projected tips. this/these are the main stay of choosing a nitrous plug regarless of heat range, copper electrode tip and non projected tips are the answer.

OK One more time. The harder Metals are ONLY for longer life. The only advantage is longer life. . . .N/A
Robert is right about the projected tip. I re-wrote my first reply so many times I forgot to include it
IF I get back from the track tomorrow (if things go well with a video of a 9 second pass in my DD) I will see if I can get a shot of a good reason to run good plugs

Brad, I agree with what your saying, as well as Robert...however for the occasional nitrous user the iridiums are a good plug. Would you want to run them in a larger shot, purpose (nitrous ingestion) built machine, no, but for the more versatile/stock type setup with smaller shots, great plug.
No matter what plug you run, checking them needs to be a religion, not a post-use diagnostic tool.
There are some ppl that dont believe in using non-resistor plugs like NGK....so many options. I prefer to stick with what I know will work, TR6/8 etc..

yeah I would most likely stick with the regular tr6 anyway, they have worked great for me. TwoFast, got ya on the longer life thing, thats all i was owndering, I wasnt sure if the irridium had different dissapating properties than copper.
#20
I just scanned through the thread, and I didnt see anyone bring up this point.. but it also says on the summit page that it requires less voltage.. = less heat, kinda. It requires less voltage to fire the spark than a standard tr6 because the iridium is a different chemical makeup (actually, 2 less free atoms in the valence.. breaking this down real far would make it a better conductor..)
Maybe Im analyzing this incorrectly, but isnt that exactly why platinum/iridium plugs are used/wanted in most vehicles (non n2o) because of the clean/even burn with an even spark output with lower voltage requirements. That would mean less fuel consumption because the plug is more efficient. Bring some real tech gurus in ehre and you may be able to get some better analyzation.
Maybe Im going the complete wrong direction.. lol
