E3 Spark Plug E3.48 Automotive Spark Plug
- 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

Was looking for a better plug did some research on these E3 spark plugs
I used to use Bosch IR Fusion (4501) swear by them for over 10 years in my 03 Toyota Corolla. Was looking for a better plug did some research on these E3 spark plugs, was very leery about attempting to put in my car took a chance and very happy I DID!!! Very smooth on acceleration then Bosch (4501) also idles perfect like the car is not even running, better gas mileage gain 3 more MPG from Bosch (4501). Now will NEVER use Bosch spark plugs AGAIN!!! Can't beat for the price, half the price of Bosch(4501). Live in Las Vegas,Nv took the chance and paid off. These E3.48 made a BELIEVER!!!! Hands down.........

E-3 Spark Plugs Do Work Well
Best spark plugs bar none. All e-3 spark plugs that I have used have been a cut above all others. I can tell stronger smoother power and better gas mileage. They are a bit pricey bur the ones I purchased through Amazon were cheaper that the e-3 website price. I would highly reccomend e-3 plugs and to order from Amazons store. I hope that this is some help. I have nothing to gain from posting a comment. Just to encourage someone to enjoy the improvement in spark lug technology.

Better than Awesome Spark Plugs
Put these in a Honda Ridgeline (which are notorius for bad fuel mileage) I went from 18 mpgs (hwy) to over 22.5mpgs. That is a VAST improvement for a vehicle this heavy. Not only that it starts much easier, runs much smoother. E3 plugs go in all of my vehicles these days.

I installed these in a 2000 Honda Civic Coupe EX ...
I installed these in a 2000 Honda Civic Coupe EX. The first month I didn't see much of a change then boom! 4 mpg extra! My car is suppose to average 26 mpg highway and I'm now getting 30+mpg depending I keep my foot off the accelerator and put it on cruise. Its 04/06/2019 and plugs have performed great for the 2 years with 29 - 35 mpg. However within the past 2 weeks I kept getting a check engine light with misfire on cylinder 2 and 4. I found cylinder 4 the metal at the end had corroded and burnt away. Cylinder 2 appeared to have badly burnt sections. Gas mileage suffered 21 mpg. I replaced with Bosch Double Iridium after I did not receive any info for warranty replacement. I still regard these as an excellent replacement plug. Five Stars remains for the plug. As for the warranty phase - you be the judge.

Immediate gains in performance!
I installed these yesterday in our Honda Ridgeline and Jeep Patriot and noticed immediate gains in performance. I'm curious to see if an improvement in gas mileage will be noted. I'll update as I do track the Ridgeline so I'll be able to tell.

Gas mileage is the same if not a bit better..
Installed in my MKV Jetta. No issues so far. Has been a month. Gas mileage is the same if not a bit better...but my last plugs we're 80k old so... They looked quality and I really appreciated the price per plug. These are 12 bucks from the dealership. Disclaimer: I am an automotive technician and I replaced these myself I highly recommend sticking with manufacturer OEM spark plugs you may end up paying for it in the end. To me it was worth it because I can do the work myself so if I have to replace them it's no big deal.

Wasn’t that hard to install. You just need pliers to pull off the spark plug “boots.” Don’t pull by the wire, pull by the rubber piece. You’ll mostly likely need a 5/8” spark plug socket, and a wrench with a swivel head is best. After installation I took my 2000 Dodge Dakota 3.9L V6 Ext. Cab out for a drive. Immediate and noticeable gains in acceleration. My truck switches gears a lot faster and doesn’t ride as high on the rpm’s before shifting now. Sweet spot for mpg is at about 55mph now instead of 50.

Great product!
Second time I have purchased them for a 2003 Honda Civic hybrid...I don't want to jinx myself and have this one end up like the last one.

Works Great in our GENERAC XG8000E 410cc Portable Generator!
I had been using the original E3.48 plug (gapping required) in our Generac XG8000E portable generator with great success for several years, so when it came time to do our yearly maintenance I purchased another E3.48 and a couple of extras for future maintenance replacements from Amazon.com. Generac recommends that the plug and oil/filter be changed every 100 hours of use or 1 year/season, which ever comes first. (The OEM plug for this unit is a Champion RC14YC and the E3.48 is the cross referenced replacement in the E3 lineup.) When I quickly ordered the new plugs I hadn't even noticed that the plug had been so radically changed to this new Diamond design until the plugs arrived! No Gap adjustment required huh? At first I was a bit dubious about putting one of these into the generator since the original version had worked so well after setting the proper gap (0.030) which the manual had stressed was vitally important for proper operation. But... I figured that I would never know if these actually worked in the Generac unless I tried one out, so I pulled the old E3.48 and installed one of these newer versions. I had been so pleased with the original E3 plug that I was wondering to myself if it would be difficult to locate and purchase the original version if this new design failed to work as well. I needn't have worried! :o) The generator fired right up without complaint and settled in to a nice smooth a noticeably quieter 30 minute test run. Since then the new plug has been working great with no issues at all, and just like the original E3 we had been using before, this plug makes a noticeable differerence in fuel consumption which is particularly important for a full house generator during our often days long winter storm caused power outages with daytime highs in the teens and low 20s! Weather conditions will often conspire to prevent you from heading down the mountain to the nearest gas station with power to refill our 4 five gallon reserve tanks we use for this unit. So obviously, the more runtime you can get out of every precious gallon of fuel the better! So... While our application is far from as demanding as those using these in a motor vehicle, reliability is no less important, so I thought I would post this review primarily for those who may be considering the use of this high tech spark plug in their portable generator. I can say that after running the E3 brand for the last three seasons, it is the only plug I will consider for our Generac! And based on the performance of the newer design so far, the new and improved E3.48 should do an even better job than the original design with the conventional GAP adjustment required design. And I do have to say that its nice to not have to worry about gapping the replacement plug anymore! One less thing to worry about when the time comes to do our yearly maintenance on the XG8000E!
