NB: The best spark plug for your car is the one recommended in your owners manual. This is just a demo. A lot goes into the choice of spark plugs, it's not just about spark. Engine design plays a major role. Copper spark plugs are best for some engines, while iridium is best for others. 🙏🏼

The actual spark energy doesn't change much. The copper is more conductive actually.... while iridium and platinum have a much higher melting point and erode much more slowly, which is required for the finer tips. The smaller area of the finer tip provides better resistance to fouling. The higher temperature and harder platinum and iridium, in particular double iridium and double platinum are for twin post coils, where one operates in normal polarity, the reverse polarity side usually rapidly erodes the electrode and ground strap, the double platinum and double iridium hold up much better here.

Type of plug may have played a role in the improvement you witnessed. Double electrode spark plugs have an advantage in being less prone to misfire plus longevity.

there is a bigger spark pattern on the copper igniting the fuel mixture sooner probably. the only reason to use iridium is it lasts longer. i wonder if you had multiple parallel circuits internal to a spark plug that could fire multiple electrodes at the same time, if that would produce better power.

[@DIYAutoworksNG]

What most people wont instantly recognize is that the plug on the right will make for better combustion. The iridium plug will perform worse simply because the iridium core is undersized due to the cost, and might only be tipped with iridium. The NGK plug has a larger spark.

[@DIYAutoworksNG]

That's if spark is the only parameter being judged. Resistance to fouling is another issue, with fouling, performance will drop and copper is more prone to fouling. It really boils down to the engine where the spark plug will be fitted.

Ngk for Life

[@Johnny53kgb-nsa]

I don't recall which spark plugs Ford recommends for their 2006 Ford five hundred limited, but, should I stick with the same brand they recommend, or would it be better to use a NGK plug for my car? Thank you, John

You may choose to stick with the same brand, or use another brand e.g. NGK with the exact same specification. Personally, I stick with the brand recommended too.

Curious why you didn't use both the same brand, but cool demo.

Thanks! On brand, I'm pretty sure it won't make a difference to the naked eye, but I agree it would have been ideal.

@@DIYAutoworksNG Yeah def would be similar. NGK does have multiple tip sizes for their fine metal plugs though. I believe 1.0 and 0.6mm from memory, but could be off. So would make for a more stark contrast!

I agree!
