- Near elimination of performance inhibiting carbon deposits, dramatically longer plug life and a 5-year/100,000 mile limited warranty
- DiamondFire electrode technology that creates a superior spark and resulting flame front extending further into the cylinder, producing more localized pressure
- Significant potential power increase: > 6% to 12% (depending on engine class)
- Significant potential fuel efficiency improvement: > 4% to 13% (depending on engine class)
- Drastic potential emissions reduction when used in 2 and 4-stroke engines (after 50 hours): 58% CO emissions reduction, 42% hydrocarbon reduction
Product Description
The exceptional performance of the E3 spark plug starts with the unique open architecture of the E3 electrode. The design forces air gap discharges, creates the preferred edge-to-edge spark path, allows free replenishment of the spark zone with a fresh fuel/air charge, and exposes the flame front more directly to the piston head than other plug designs.Sparks naturally follow edge-paths as they leave an object. The E3 design presents multiple sharp edges to the cent… More >>

Just installed a set of E3 plugs in my 08 Hyundai Tiburon SE V6… fried out the original plugs in 21K miles and was running a bit rough. The new E3 plugs netted 30.1 mpg on the first tank after the change and 30.4 mpg on the second fill up. The original plugs were still getting around 26-27 so I like the new plugs. The car starts better and runs more smoothly so I would say these are winners. I also put a set in my 06 Sonata V6 and have noted about a 2 mpg increase there too.
Overall, these plugs seem to live up to the hype. I have read mixed reviews but am on the plus side with these little beauties. They aren’t expensive and would be a good choice if you are doing a tune up.

Was very impressed with these plugs, the rule of thumb is that it is pointless to buy anything but platinum plugs but these have actually helped even out my burn KV and evened out burn time !!

I own a ‘93 Honda Del Sol 1.5 Si base engine with fuel injection. Trips taken in this vehicle can be long 350+ miles and return the same day. Until recently unrefueled range on the car was 280 miles; since putting in 4 E3 spark plugs range is 340 miles at 70-75 mph. I have tried Bosch +4, Split Fire, and NGK platinum.
This plug’s performance in my vehicle is superior; it yields greater gas mileage, torque, and speed.

I drive an ‘01 Nissan Altima. I put these plugs in after seeing them tested on TV. I got an instant increase in power, and so long as I keep my foot out of it, I also get better mileage. E3’s ads are true accross the board.

Installed these spark plugs about two weeks ago in a 2004 Saturn Vue. Better starts. Have not noticed any increase in fuel economy, though. I think there are some other things going on. May need to replace the coil-on-plug packs, as they have 140000 miles on them.
