Denso iridium IT20's for a 2000 with 75 shot of nitrous and later on a 4# pulley. Will this plug be ok with this setup?

 

I think I would go with IT-22s if you are going to use nitrous. Or you could use a copper plug like a BR-7ef.

22's or 24's.

Hotter plug will probably just burn the tips off faster if the nitrous tune is off.

I ran 6lb lower with a ported blower on stock plugs for months, no problems. Changed to cold plugs and still couldn't run even one degree more timing that with the stock plugs.

If you haven't put them in yet, then probably go with the 22's in the end.

 

Ok so It22's ill get, will the iridium be ok with the nitrous?

 

So are iridium plugs ok to use with nitrous???

 

NO iridium.i tryed the densos it22s and and it ran really good but they are just to fragile and expensive.went to br7s but only lasted a couple of nitrous passes( i dont know about u but i dont have the time or the patients to keep changing plugs)the best plug that worked for me was the autolite 103 ive had them in for over a year with alot of nitrous passes and still look good i just changed to the imfamous tr6s a couple of weeks ago so we will see how those work out.good luck
