Default halo spark plugs

i come across this today
and thought that would be kind of cool to try, they apparently have lots of testimonials and are constantly doing tests for it. Might be snake oil, but might be worth checking out.

They have a very Amsoil-ish website. I better duck before the Amway....I mean Amsoil dorks attack. They look like knock-offs of the Torquemaster plugs that have been around forever. Try 'em if you like, but I would guess they will net you nothing over what you have now. Most of the spark plugs' claims and customer claims come from testing old, tired plugs and then the new whiz bang plugs. They see a change when new and claim spark plug utopia...they almost never do back to back new vs new testing and certainly consumers never do this.

So if you are bored, give them a shot. I'd personally recommend reading the Spark Plug FAQ and trying one of the fancier plugs list there vs these if you are really interested.

Snake oil.

Here's why: Notice the newest plugs in the industry have very small tips on the center electrode? When the plug sparks, you get a small "flame core" that starts to spread through the cylinder. When the flame core is first formed, it's very small, and does not contain much energy. The more material you have surrounding that baby flame core, the more energy is absorbed. If too much energy is absorbed, a misfire will happen. This effect is known as quenching. This is the reason for smaller electrodes as seen in platinum and iridium plugs, to reduce quenching. The less quenching you have, the more energy will make it to the rest of the combustion chamber.

Now that you know this, compare the halo plug to an iridium plug, and you decide which would perform better.
