## Description

Product Description The E3.48 auto spark plug is a high-performance 14mm, 0.750-inch reach plug with a gasket seat, designed to fit a wide variety of late model applications, particularly import vehicles. Known for its durability and performance. Featuring a unique design, it secures the patented DiamondFIRE electrode with three legs, allowing for excellent heat transfer and creating more turbulence within the cylinder for optimal combustion. The DiamondFIRE side wire is proven to increase engine power, reduce fuel consumption, and improve hydrocarbon emissions over long-term use. The plug's unique ground electrode and full-size center electrode ensure optimal performance, providing reliable results for up to five years or 100,000 miles. With a fixed gap design, the spark plug boasts a DiamondFIRE open structure that forces air gap discharges, creating a superior edge-to-edge spark path. This advanced design enables replenishment of the spark zone with a fresh fuel/air charge, exposing the flame front more directly to the piston head, which improves combustion efficiency. As a result, this spark plug increases engine power output, reduces gasoline consumption, decreases hydrocarbon and carbon monoxide emissions, and extends the spark plug’s lifespan. Perfect for lawn and garden equipment, it ensures faster, smoother acceleration and improved engine performance. desertcart.com

Review: Excellent plugs - I watch "Gears" (a show that admittedly looks like E3's bish...) and "Horsepower TV" and both shows tout the benefit of E3s design. I've read a lot of negative reviews, and a lot of positive reviews. At 300 miles so far, and all seems to working just great. (smooth idle, good power, increased mileage.....) but these plugs replaced plugs with 70k miles, the fuel filter was many months over due for replacement, and the tires were 10+ pounds low on pressure, so naturally my ride seems quite peppy and smooth. (94 Accord with a 2.2L standard trans). So I can say these plugs are an excellent replacement for the aged plugs, but I corrected too many problems with the rest of the ride to quantify that the plugs made my ride way better. My best MPG ever (city) was 28mpg, and the reason for all of the "fixes" was that my avg MPG was dipping towards 26. That said, if my MPG gets back to 28 or better, then these plugs are definitely a good investment.
Review: 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 desertcart.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!

### ⭐⭐⭐⭐⭐ I installed these in a 2000 Honda Civic Coupe EX ...
*by R***5 on June 11, 2017*

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.
