Which spark plug for 515ish RWHP
Which spark plug would you guys use on a 2010 camaro with 515 RWHP with a a big cam? I know the stock spark plug is rated 5 for heat range so the next step would be a 6.
Should i apply 1 colder heat range for each additional 100 RWHP or 2 colder heat ranges? Would you go 2 steps for a: NGK BR7EF or NGK Iridium TR7IX Or well just 1 step ahead to a 6 heat range numbered spark plug? NGK BR6EF or NGK TR6IX thanks for you comments! |

I'd try the 1 step colder Iridiums and see how they look after a few hundred miles. Better to err on the cold side.

NGK TR6 stock number 4177 NGK. NGK plugs the higher the number the colder the heat range with some plugs the lower the number the colder the heat range.

tr6 and see how they run, probably will load up at idle and low rpms, go with a tr5 gapped at .035.
the br plugs are for nitrous. don't waste your money on iridium. nothing performs better than copper. |
