E3 - DiamondFIRE Automotive Spark Plug: More Power, Saves Gas (Part No. E3.74)
DescriptionThe Spark Plugs are the product of years of fundamental research in the combustion field. The unique patented electrode configuration of these new The 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. E3.74 is a 14mm, 1.000 reach plug with a taper seat. It fits a wide variety of late model applications, especially Ford applications. The automotive plugs have three legs securing the Diamond FIRE electrode to the shell. This allows for excellent heat transfer, and helps to create more turbulence in the cylinder. The patented Diamond FIRE side wire is proven to increase power, reduce fuel consumption and improve hydrocarbon emissions in long-term use.
Product Features:- E3's Diamond Fire edge to edge ground electrode provides maximum performance with increased efficiency and a faster more complete burn
- Smoother Acceleration & Idle - The faster flame initiated by the The spark plug results in a more complete burn of the ingested fuel charge. More pressure is created against the piston more fuel is put to work
- Energy - Power output improved up to 6% on average in the typical operating ranges. Results will vary.
- Efficiency - The "diamond shaped" side wire electrode projects the combustion spark in a way that more quickly ignites the air/fuel mixture, thereby creating a significantly faster and larger flame kernel. The result is that more fuel is put to work during each combustion cycle.
- E3's patented Diamond Fire Technology provides a cleaner burning combustion, which translates into fuel savings and reduced engine carbon deposits
- The Spark Plugs are pre-gapped at the factory and cannot be adjusted.

Pulstar Spark Plugs, manufactured by Enerpulse Technologies, brings plasma-assisted combustion to consumers with a simple spark plug upgrade. Pulstar uses a patented internal capacitor, developed with the help of a US DoE laboratory, to create a high-intensity electrical pulse that ionizes the air-fuel mixture and saturates it with combustion-enhancing plasma. With its plasma-assisted combustion, Pulstar ignites fuel instantly and burns it rapidly; gaining up to 7 horsepower, 9 ft.-lbs. of torque ... and, delivering wicked throttle response.Read 1 review(s)Review snapshot ® by PowerReviews

I read many reviews of these spark plugs, some good, some bad and thought that most people were not following the instructions. So I took my time, gapped all plugs properly, used a touch of anti-seize on the threads and a little dielectric grease on the boot and plug tip. The plugs worked as advertised for a short trip to work (15 miles) but were misfiring before I could make it home. I tried calling the manufacturer but they just put you on hold indefinitely (2 times over 45 min hold), tried emailing their service dept with no response. I have filed a report with the BBB and now waiting for a response. Would never recommend this product.
