Have you heard any positives or negatives about these spark plugs? I was thinking about getting them because of their increased spark but I am curious if the increased spark would cause a decrease in motor dependability because of the increased spark at the piston.

 

There is no reason to try another spark plug other than OEM in an otherwise stock S2000 motor. Honda did a thorough job engineering this motor and there is no gain to be had in the spark department.
Most aftermarket spark plug companies that make claims of incredible gains are nothing more than marketing. Inevitably these miracle spark plugs cause problems - significant problems in in many cases.

There is a lot of information in the FI section regarding application specific spark plugs for several FI applications (turbo, supercharged, NO2).

Long of the short - stay with OEM unless you supercharge or turbocharge your car. If you go that route - go to the FI section and benefit from the significant amount of work others have done before you. Many times it's involved significant trial and error - and/or research - which has played out over the years. Then go with what has worked best for your specific application.

 

The s2k has never suffered from lack of spark.

I wouldn't even think about anything other than oem. They have proven to go ther distance.

 

more spark means less spark plug life.

 

Take a 20 bill and set it on fire.

 

or give it to me!
