So far so great!
I purchased these for my 1988 Silverado 5.7. I noticed a little more power. I just put them in a week or so ago so I am hoping to see a gas mileage difference also. So far they have worked great!

E3 spark plug 89 S10
After a few weeks chasing down a poor idle, I found the reason. This can happen to any brand of plug BTW.Over all, I like them. Seem to have a better response and smoother acceleration.Chevy S10 4.3l with just Ober 300k

E3 Spark Plugs - nothin' but the facts Ma'am
My K1500 Blazer almost failed the dyno hydrocarbon smog test the last time, it was a borderline HC 78 ppm, the CA state max at 15 mph.I have been reading about the E3 spark plugs, and thought that I would install them replacing the Bosch U grove platinum plugs that were in the truck. Not only does the truck feel peppier, but it now idles dead smooth with the new E3 plugs.Here are the dyno emissions before and after the plug change:15mph - HC was 78ppm now 55ppm, CO was 0.25ppm now 0.12 ppm, NO was 587 now 373.25mph - HC was 37ppm now 28ppm, CO was 0.11ppm now 0.08ppm, NO was 249 now 136I can't believe it, they really do help the combustion process, at least in my Chevy 5.7.I have tried a lot of snake oil products, coil boosters, various spark plug designs, all without any positive results. This is the first time I havehad concrete results with an ignition product!

Edit: had to remove after 20k miles
Put these in my 94 camaro. I have no idea how long the old plugs were in the car.Ran smoother right away.Miles per gallon increased From 22mpg at 75-75mph, to 25 mpg, after the plugs broke in after a few thousand miles. Increase to 23-24mpg instantly.A lot less “sluggish” days. Engine runs better on 87 octane.Edit: I believe a plug went bad after 20k miles. Had to remove. Went with traditional style iridium. Definitely lost a little kick compared to the E3s
