So doing some work on the Expy. Not putting plugs in until I get it tuned. Are you all running the NGK Iridiums and if so which ones? Much appreciated for the input and happy Friday.

Check out this post (it covers some other stuff but skim through until you hit @LokiWolf posts and then start looking for spark plug talk).So doing some work on the Expy.

I can concur with Loki, these are the plugs I've used and I actually just ordered another set, just about time to replace them again.What @Alwaysthinkin said...
These are the plugs I recommend. Stock, do 0.031, tuned or always run 93 and hard, do 0.028.

I replaced my OEM with the Ruthenium's as LokiWolf stated. My '20 did some "trailer hitching" a couple of times at 45K, that's when I changed them. It has run great ever since.What @Alwaysthinkin said...
