I already have NGK-TR6 plugs in my truck and it time to change them. Would there be any benifit for me to go to TR8?

Blown or NO2 I would go with the TR55 ix's they burn colder and should be good w/ your procharger.

aren't they the same as the stock heat range? The tr8 is like 3 heat ranges colder and the tr6 is one heat range colder.

I thought the tr55 was stock too. I am running the tr6 plugs now, but I would be interested to know if something else is better.

Tr6 is good for high compresion or FI, tr55's are stock.

I orginally posted this in the forced induction room but they moved it. I was wanting to hear from people that are running the same setups, supercharged and turbocharged. I dont know why they moved it. I guess i will repost over there because I would get better responses over there.

I run TR6 gapped at .30

Ditto for me...TR6s at .30 seems to be the magic combo.

Next time just post the topic stating "Which NGK Spark Plugs With FI"
That will keep it from being moved.
