spark plug question

A colder plug will make more power but have a better chance of fouling correct?

This is one of those it depends on a lot of factors answers. A hotter spark will burn everything and is sometimes needed. If your plugs are that nice brownish color replace them with the same plug. If you have wet plugs or a little oil a hotter plug may help, but be aware there is something else up. There is also a need for hottor plugs to burn Nitrous, etc, etc.

Re: spark plug question

I emailed ngk my motor specs and they recommended I use one step colder than stock in my motor. Just wondering if this will make more power or be more of a hassle?

Re: spark plug question

Last trip into the local speed shop, they knocked me back a number or 2 on the plugs......yes it does make more power, as long as they arent too cold(then they foul ). I havent had any troubles with the colder plugs, but its "experimental". just dont spend the bucks on platinums, till you get the heat range sorted out best of luck,crazyL

actually you run a colder plug for Nitrous..the Nitrous increases the cylinder pressure...kinda like forced induction...effectively inceasing the compression ratio
