I am gonna try some Denso IT-20's anyone know the correct plug-gap ? 4lb lower,Ported Eaton,Bassani,Fast-air PSP . Thanx !

 

Talk to Suavy about Denso before you spend a rediculous amount on them...

I had them, but switched to NGK tr-6.

 

I don't have the ported eaton but I run mine at 36 thousandths.

 

.033 and get the it-22's for saftey being they are a colder plug.

 

Some Love them, some dont.

I LOVE THEM, and agree with Bryce you should use IT-22's, cooler plugs add safety. I've been using the same set for whats now their 3 summer and they perform flawless from 600 RPM to 6000 RPM. I also run 6 to 9 very differant set ups and they perform perfect in each differant one. I run a .038 - .040 Gap but I also have a Multi Spark Set Up and that allows a larger Gap.

 

If I were you I would check out the new Brisk plugs. About the same price as the densos, but should last twice as long. Some people are claiming some respectable power gains with them as well.

Thanx Guy's ! I've had the denso's for awhile but never installed them. Next time I will go It-22's or Tr-6

 

You can buy them pre gapped form outrageous preformance.

 

I dont mean to jack your thread, but i have 4 lb lower, stock upper, and I need to know what ngk plugs to run, tr6's ,or the br7. I am think the br7's because they are safer. I also need to know the gap.

thanks

I have a 4#, ported eaton, and put down 428 too!

My tuner had me change my IT-20s to 0.032" (from the 0.04" I was at) Saw a difference too.

Thanx! But won't the tighter gap Melt the plugs faster ?
