Spark Plug Help

[Bob Hughes]

I'm putting my blower on this weekend......and tork tech says I should drop a heat range on plugs....they suggest ngk tr6 plugs....what would that equate to in autolites or motorsports plugs....any knowledge greatly appreciated

Go with the TR6s, they are probably the best. I ran autolites with my Kenne Bell just until I switched from the KB tune to a dyno tune. Autolite 103s are heat range 6 copper plugs.
