- 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 >>

Purchased these and installed 6 months ago. Already had one foul within 12,000 miles. I did not see a sufficient improvement in gas mileage and I do track fuel usage. I am sure it may improve gas mileage but for the fact they foul prematurely and the time it takes to replace it is not worth it.

Put a set of E3’s in my Ford explorer. Started throwing a bad cam sensor error code. Replaced the cam sensor and servo, same error code. Replaced the plugs with the Accel’s that were in there before and no more error code. The E3’s are apparently not insulated properly (which may be why so many complain about failure) and they can and do put out stray radio frequencies that the computer cannot understand. Wouldn’t waste my money on E3’s.

I saw these plugs advertised on the show Gearz TV. The claim was improved gas mileage over standard plugs. Maybe so but I couldn’t run them long enough to find out. One of the plugs fouled out in about 2 weeks and according to the markings on the ceramics on the business end of the plugs, a second one was well on its way to fouling out. I had a ASE Certified Master Mechanic check my truck after it started running ruff and his computer identified the bad plug. We changed them out and went back to the AC plugs and all is well. The only bad thing is I had to send them back to Amazon and only got $38 of my original $48 purchase back and that is after I had to pay a mechanic $50 for a diagnoses and another $60 for the AC plugs and installation. “Live and learn!”. rc

I bought a set of these for my 2005 PT Cruiser GT Turbo and paid $8.95 per plug. The plugs seemed to produce
more power, yet made my car miss BIG time. There was a stumbling that was not there before the E3’s. Ended up replacing the E3’s with stock plugs and that took care of the missing/stumbling. Thankfully, the company refunded me for the plugs. “If it sounds too good to be true it probably is” Better mileage? More power? Big mistake buying the E3’s.

I put the plugs in 6 mos ago, truck ran great for a while then one morning, check engine light and a BAD misfire. Plugs only had @ 5k miles on them. Replaced them with AC delco plugs and problem is gone. From what I have read, mine is not an isolated incident.
