Hello,
I have a 2019 Hyundai Accent SE, automatic, with a little over 31,000 miles on the vehicle. My car came stock with iridium plugs. I heard good things about E3 spark plugs, and was curious what if any offerings were available for my car. I like getting more "economy" (Fuel economy. That's their main selling point, and most common praise) out of my "economy car".
The E3 website part finder had an offering for the 2017 Hyundai Accent SE, but not 2018 or my model. I emailed support and a rep assured me that their database, a national database, updated twice a year, was current. There was no option for my vehicle.
Is it normal for such a simple, albeit important, component to become incompatible in such a short amount of time? What factors could cause this that my naive, impulsive, impatient brain neglected to consider?
Thank you,
Al
snake oil and fool's errand I think.
the job of the spark plug is pretty simple : ignite the mixture.
I don't think there's much room for significant economy improvement there.
I heard good things about E3 spark plugs,
How much more money do these things cost? Will the benefits EVER pay off?
neglected to consider
yeah there are FAR, FAR more important factors that affect economy. (which are discussed in detail in our FAQ)
It's hilarious how far people go (and how much money they spend) to chase economy (like removing a piece of plastic on their engine for "weight saving"), but nobody changes their driving habits, which is completely free and makes a huge difference.
E3 spark plugs are a scam. Use the spark plugs listed in your owner's manual maintenance section.
Doesn't seem to be much information out there that isn't either from their marketing people or just anecdotal. So hard to be definitive.
But in general, the differences in spark plugs are more pertinent to longevity rather than performance. For example, platinum and iridium plugs last longer than copper. If there is a significant difference in performance to be had, I suspect it would be in an older carbuerated car rather than a modern fuel-injected one. The ECM will adjust spark timing and all that electronic stuff automatically, and so there is little to be gained by a fancy plug.
If anything, I would stick with the plug type that the engineers assumed would be there. If there was a better plug, the engineers would be using it already.

They're not even a new scam. Here's an ad for a similar type spark plug in the February, 1956 issue of Popular Mechanics magazine:
It's best to stick with plugs of proven design, as specified by the vehicle manufacturer.
but more is always better! right?
