What Spark Plugs do you use? I was just wondering what the common spark plug is all you fellow LS4 guys use. I won the Bosch Iridium Plugs from the contest on this site 
and wanted to get other opinions. I think my car still has the stock plugs in it so I am probably due.
Thanks

NGK TR6IX Iridiums... which are one heat range cooler than stock plugs.. and gapped to .035 instead of stock 040....

I just swapped mine to TR60's after my tune, not sure if that was a good choice though because I'm already losing pressure and heat being at this altitude. Probably going back to 55s again to see if there is any difference.

I use E3's they seem to work fine and my tuner did a datalog and he said there were no misfires. Basically just expensive spark plugs. My buddys impala ss with stock tune gained a bit in gas mileage lol

the thing i like about the E3's is the rounded thread to prevent seizing. The previous owner of my dads truck put Bosch plugs in it and they all seized up and it took him 4 weeks (working on them on the weekends) to get them out. So thats the only worry i have about Bosch plugs
