I have a 1997 vw jetta 2.0l with 215,000 miles. about one and half years my mechanic with out consulting me installed Denso iridium not the top of the line but iridium with about 18,000 miles. In the morning cold star a vibración was really bad and milages was worst. Las saturday I bought and installed E3 .48 and I have a new car ,I am amaze the shaking is gone and the milage which am testing with my first full tank just cant believed what I am seeing, and last but very important I can feel much power not using second gear climbing the mountains of my home town Barranquitas Puerto Rico 2,000 feets above sea level. My best investment in spark plugs ever. Highly recommended.

Excellent Product
I just wanted to let you know how pleased I am with your spark plugs. I just changed the plugs in my 2004 Saturn VUE. It has 595,300km on it and I realized that my E3 plugs were overdue for a change. Checking my records, the last set of E3 plugs have been in 387,234km and it still is running great. I was amazed how good they looked when I took them out. Since I had already purchased new ones I still changed them. This is the second vehicle that i've put E3 plugs in and I continue to get better performance, fuel economy and plug life. I've also recommended E3 plugs to friends and they are ALL impressed. I can't understand why anyone would use anything else.

Excellence X3
I have been having issues with fouling plugs or the plugs just stop working while I am running autocross in my MG Midget with a Nissan sr20 swapped into it . Since i switched to the E3.48 I have noticed my air fuel ratios back up where they should be , and more power coming out of the corners . I am very impressed and am going to be spreading the word

E3 Spark Plugs, Definitely Worth Your Purchase!
I purchased E3 spark plugs for a 1997 Honda Passport that had been misfiring, and since replacing with E3, I have no longer had any misfires and it has all around seemed to be running better, firing smoother, and being more fuel efficient. The fuel efficiency was almost immediately noticable. These plugs are definitely worth your buy, even if you are hesitant at first as I was. I was using NGK almost religiously until I found these, and trust me, the difference in the product is truley incredible. You won't be sorry!

Hi all. This is my 1st purchase of E3 plugs. I was hesitant and cautious. ya know new design, hype, advertising etc. I am VERY satisfied though with my purchase for a few reasons. I have been a shade tree mechanic for over 30 years, these are the only plugs that have threaded completely in by hand! Keep up the engineering and manufacturing process! #2. the gas mileage increase was instant. I was averaging 36 mpg in my 2005 Prius around town. I am now up to 42 MPG! (no hwy stats yet). #3 The engine prior to install was lagging and downshifting allot and shifts were abrupt. Well all those issues are gone as well. You have made a new customer. I will only install E3's in all my vehicles from here on out.

Great for performance
I’ve run these plugs in my Miata’s high revving engine for multiple HPDE’s and got no ignition break up or misfire like I would get from other brands on the hotter days with higher intake temperatures. I also found myself changing plugs far less often than when I was running brands such as NGK and Champion. These plugs provide a much more complete burn and when I remove the plugs the color is consistently the same. I highly reccommend these for daily drivers as well as performance applications. These are the best plugs I’ve come across.

Awesome Product
I ran these plugs in my '93 MX5 and had great results. The car ran better and felt healthier than it did with the NGK's it had in it when I bought it. I've also ran these plugs for my '94 Integra with similarly positive results.

Definitely made me a fan of the E3 brand!
more power, reduced emissions, improved fuel efficiency, longer life, faster starts
