E3 - DiamondFIRE Automotive Spark Plug: More Power, Saves Gas (Part No. E3.52)
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. E3.52 is a 14mm, 0.375 reach plug with a gasket seat. It fits a wide variety of GM applications from the 50s to early 80s, and is generally the correct plug for older small block Chevrolet engines. 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.

I have a 1996 Mazda Protege with 150,000 miles. I replaced the plug wires and plugs. I noticed a cylinder with oil in it so I purchased the non-fouler thinking I would use it until I had a chance to make the correct repair. After driving about 3 miles the porcelain part of the plug blew out leaving the plug base in the non-fouler. This happened 2 more times with about 8 miles being the greatest distance driven before it happened. I removed the non-fouler and have been driving the car since with the occasional fouled plug.

Pulstar - Spark Plug with PlasmaCore (Part No. BE1H10)
DescriptionPulstar Spark Plugs use innovative plasma-assisted combustion technology to increase horsepower and torque.

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 3 review(s)Review snapshot ® by PowerReviews

These plugs are so bad due to their low quality. I thought I lost my engine yesterday. Only about 20 days and 500 miles since I installed them. Just on the highway on the way home at 65 MPH yesterday car started running not on all cylinders, it was running so bad i was sure the engine was finished. Just made it home. After cleaning up the mess it made on the top of the engine I found the top of the spark plug had exploded and the central terminal had ejected from the plug, so it was like the spark plug wasn't even installed in the cylinder, hence the mess. When I say the top of the plug exploded, I mean it really did exploded, it even blew up the spark plug boot that was on it. Granted these plugs did give better low end power than the stock plugs, but based on how they failed, they are clearly low quality and not reliable enough for daily use. Please save your money and time.
