Tr-55 in my opinion. I see no reason to go as cold as a TR-6 for that.

Those are still the same heat range, just depends on whether you want a expensive plug or not.

run the 55. if there is carbon on more than three threads, change to a 6.

the IX is an iridium plug.

Run the TR55 for 1/3rd the price of the IX. The IX is a waste of money imho. My truck eats them up

I think mine feels the same way. I'm actually running the tr5IX. and it has a nasty misfire around idle. I may go back to the tr55's. What should I gap them to?
