I'm running my stock plugs gap at 32 and my acceleration is choppy at part throttle but awesome at WOT. At 10psi Vortech v3 auto car. I'm needing to get this 6510 and hopefully it cures my problem. .
I do what ever my tuner tells me so 6510s will go in. If he told me to lace them in dog shit I would ask "what breed?" Want my car to run smooth and be safe.
These are the plugs we used in Rebecca Starkey's 5.0 TVS That went 9.79 1/4 we have them in stock and can get a set out to you. We recommend these plugs for the 5.0 with a blower. We also have these in our 2012 Boss making 843rwhp and they are still good. PM me or email me for pricing. In stock.
You can get these plugs for half the price of AM and Autozone on either RockAuto, Autoplicity or Race-Mart. I think I paid less than $50/shipped for my set after a price match.
