Truly more bang for your buck
Best plugs ever! Had to hold my breath and make the leap the first time but, I will never buy another brand of spark plugs again for my Camaro. The third set of plugs in my new 505cid BB Chevy and wow what a difference? Way better idle, acceleration, horsepower but not yet mileage because it is way too much fun to push the gas peddle down. Price was too much, at first, but never mind that. The difference in performance was well worth the price. Gimmicks rarely ever work out, but this one did. Will buy again.Read full review

Kind of sort of
I didn’t buy these to turn my 08 Kia spectra into a ricer, so I can rice so hard. They won’t give you more than 1-2 more Horse Power. Fuel consumption is more key.they make little difference but some. I want longevity, the NKG’s, I’ve had hotter and colder plugs with various octane formats to match, are notoriously short on life span. They go down hill fast. I’d like to get 20k out of them without them drawing down. We will see, they work well with smaller displacement motors.Read full review

Went in a little skeptical...
Very noticeable difference over NGK Iridium. Better throttle response and acceleration, better cold cranking power and astounding passing power. This plug also has the best spark advance (I own dealer-quality diagnostic tools) I have ever seen without some sort of tune or other modification, and doesn’t get very hot like Iridium/Platinum does. Over a course of 2 weeks (2 full gas tanks), have gained 0.6 MPG. Have difficulty keeping under the speed limit and maintaining common speeds oftentimes, with no intention of going faster. Will definitely try them out again on other vehicles to see if I get the same result. Note that these plugs do have a copper core, so expect to replace them every 30,000 miles or yearly.
Note: I do have Becker ignition coils installed, so performance coils may (or may not) have complimented this spark plug. Read full review

Mpg increased from 10.9 to 12.5.
Installed these E3 plugs in my 94 Land Cruiser. Instant improvement in driveability. No longer have to lockout overdrive just to pull the hills around here. 100 miles of driving showed an increase from 10.9 mpg to 12.5 mpg. These are my new favorite plugs. Been using Pulstar for years, love the power increase but never saw an increase in mpg. I'll be replacing the Pulstars in my 02 Volvo V70 XC with E3 plugs. Better plugs for less than half the price. E3 has done it! Read full review

I am Groot
I have used the E3 product many times in many different applications, from lawnmowers to automobiles. I've never seen any negative side effects. I don't have the tools for measuring changes in power output, or MPG besides basic math. That being said, the rudimentary calculations I have done have yielded 0.5 to 1 MPG increase in my autos. Is that because of the design of the E3 plug? Maybe - it could just be fresh plugs, and I might see the same result with any change, but the plugs I've replaced have appeared to be in perfect working order too...
I'm not an automotive technician, just a driveway mechanic with a lot of experience wrenching on my friends and my vehicles. I've never regretted installing the E3 plugs. They are affordable, and I don't feel the need to purchase the latest, greatest unobtainium plugs, because I don't need/want my spark plugs to go 100,000+ miles.Read full review

Best bang for the buck, hands down.
Best plug I've found to date. I use them in all of my vehicles, two wheels or four. On my 40 year old mint conditions motorcycle, they added 4 mpg, and better throttle response. On my truck which this set was bought for, I gained a smoother idle and better throttle response, idk about mileage. I don't track it. The life of these plugs is 5x an ngk plug. ngk I had to replace every single year, sometimes twice. These plugs last at least 5 years in my vehicles before showing signs of needing to be replaced. I even use them in 2 stroke motorized bikes. They work awesome in anything I have thrown them in. I won't use any other plug now.Read full review

Instant better performance
After the installation of the plugs they work great. I'm 66 and the process of spark plug changing is sure different than I remember. However that being said the instant performance was noticeable. I put them in a 2008 Honda Ridgeline with 255.000 miles . The truck ran good before but these plugs make the pickup basically fly. My mileage is better, not by much but better a mile per gallon better I have only put one tank of gas through the plugs so i'm hoping for better but it's a improvement.Read full review

Pleased
When I first bought the spark plugs, I thought they would be an intriguing experiment. After installing them into my wife's car, I noticed an increase in power when I started driving down the road. So now the curiosity of how well they work and the actuality of how well they work is a real surprise. I am very pleased with the performance of the spark plugs, and look forward to using them more.Read full review

Worth every penny/cent. Everything to gain.
I was skeptic because for my 40+ years of using standard plugs and thought there were nothing better. When my much younger neighbour who is a car enthusiast suggested E-3 plugs I told him, "i have nothing to lose". I saw a drastic change immediate: faster and smoother acceleration, quieter engine and less petrol consumption per mile on a tank of petrol.When I think about, I wish was using E-3 over the years because surely I would have saves thousands on petrol now that my car's odometer is showing 177303 miles. Awesome spark plugs!!!Read full review
