which plug should i run on my app...TR6 or 7 plugs?
And why? Does a colder plug make less of a spark?Would i have to run a a smaller gap with the colder plug?I have always ran them on my nitrous motors but not sure about boosted motor.
All depends on the amount of boost, total amount of timing, air charge temp, running alcohol or methanol injection. Start with the TR6 and run them then check them.
ok yeah i have everything in my sig..my app was reffering to my application..and i am running 8lbs right off the wastegate spring.this is my daily driver and will be on pump gas with low teens for timing
