The tips have a 2-prong arrangement in addition to the center tip. The gap for my car needed to be 0. Employing a revolutionary 360 degrees laser welding process, Denso has created a spark plug unlike anything on the market today. The V-Groove center electrode also allows for more area for flame expansion. Denso is a good brand. With their exclusive Heat-Active alloy, they are.
I expect them to last about 60k miles. Be sure to check gap on any plug before installing. These innovative spark plugs are designed for durability under the most extreme conditions. I expect them to last about 60k miles. The unique patented electrode configuration of these new E3 spark plugs increases the amount of combustion pressure created during each power stroke of an engine, which results in a marked increase in power output, fuel economy, and reduced emissions in all gasoline engines. No matter the situation, Advance Auto Parts has the Spark Plug product you desperately need. Or you may just be struggling to keep it highway-approved.
Just did a plug change on my 2002 lw300 and it had these in it. Solid Copper Core provides superior heat dissipation, conductivity and a broader heat range. Bottom Line 3X longer service life compared to standard copper plugs Bosch Double Platinum spark plugs are engineered to extend performance life and durability. They've been around for many decades at twice the price. The gaps, out of the box, were all over the place.
E3 Spark Plugs are the product of years of fundamental research in the combustion field. The tips have a 2-prong arrangement in addition to the center tip. The fine wire design of the center electrode improves ignitability and performance in your engine while the platinum tip on both the center and ground electrodes ensure longer life. The fine platinum tip reduces the voltage requirements and is extremely durable under high heat combustion. The real test will be how well they hold up for the next 100k miles. They were not available this time. This is an excellent plug.
I noticed the gap between the prongs and the center tip were different and had to adjust the gap on each plug. Be sure to check gap on any plug before installing. These premium aftermarket replacement spark plugs are manufactured to meet your expectations for fit, form, and function. These premium aftermarket spark plugs have high-quality suppressors that help prevent misfiring, an improved plug to boot seal, and a pure copper core for greater durability.

The real test will be how well they hold up for the next 100k miles. Denso applied platinum to both the center and ground electrodes with superior resistance to erosion and corrosion which enables Denso to create a spark plug capable of consistent, extended operation in excess of 60,000 miles. Four-ground plugs are a gimmick. Trapezoid shape ground electrode provides excellent flame reproduction. Machine rolled threads to reduce cross-threading and seizing.
They are also available for Marine applications. Their high-quality copper cores and outstanding suppression characteristics deliver reliable performance. They've been around for many decades at twice the price. So you can drive around the Earth over 4 times, with lower emissions and better fuel economy. I think the Denso's are just fine and came at a good price. The car manufacturer gets a good deal on them, so some are factory installed.
