Different Spark Plugs Dyno'd

sparkplugs.com did a dyno test of a stock srt4. They tested a few different plugs on the same car. Better details in the link.

Kinda interesting results.

I wonder why the NGK Iridium shows good consistancy on all 3 runs, but most others have a 3-5 hp variation. Makes me think engine and tire temps were not being controlled very well.

This is just a sales gimic. No dyno is presice enough to validate gains in the 3-5 hp range. If you look at the data with that deviation you would need much more tan 3 runs and it would still not mean much.

Not saying that a good set of spark plugs is not a good idea, but you cant really claim it gives you any quantitative advantage.
