Spark Plugs for Racing?

[Lucid Moments]

They should work fine. One step colder than stock.

Can I ask a seemingly simple question?

If the stock k24a2 asked for an ik20, would it beneifit to go one step colder just because ?

NEVER MIND! FOUND THE ANSWER ON the INTRANET!

"Do I need a colder spark plug? A rule of thumb is one heat range colder for every 75–100hp you increase. In identical spark plug types, the difference from one full heat range to the next is the ability to remove 70°C to 100°C from the combustion chamber. The heat range numbers used by spark plug manufacturers are not universal, so a 10 heat range in Champion is not the same as a 10 heat range in NGK or in Autolite. When making the decision to change the heat range of your plugs, it is a wise idea to make changes in 1 heat range increments, checking all your plugs for suitability during your test. Vehicle modifications during the test phase of your plugs is not recommended as this may skew your results."

Rule of thumb doesnt always apply as I would have to use a 12 heat range NGK plug if that were true.

No never, I dont even think NGK makes them that cold. Evans told me to run an 8 at ~450whp and a 9 at ~650whp and have been doing so ever since my tune. I have a k20a2
