Product Description

"This set of Pulstar Pulse Plugs will do more to improve the performance and economy of your vehicle PER DOLLAR SPENT than any 'mod' you could possibly be considering. Requiring only the most basic mechanical ability or a relatively short amount of professional paid technician's time to install on most vehicles, Pulstar Pulse Plugs are a 'drop in' replacement for spark plugs, and utilize technology and components that simply are not part of the design in a spark plug. The key element is called a Pulse Circuit, and it acts in a manner similar to the capacitor in an electronic strobe, storing energy that is fed to it over a relatively long period of time and releasing it during a dramatically short interval. The Pulse Circuit stores energy that is wasted during the initial phase of the spark, during which the voltage is being built to a sufficient level to cause a spark to jump between the electrode and ground strap. At the moment this occurs, energy which would have otherwise been wasted in a spark plug is applied to the ignition event, creating a spark of such energy that the ignition plume propagates significantly and measurably faster. The result? More efficient combustion of the fuel, which yields more torque and horsepower and LESS emissions, naturally resulting in better gas mileage. Pulstars are GUARANTEED by the manufacturer for as long as you own the vehicle in which you installed them. Pulstar Pulse Plugs are no longer considered an experiment. The technology is proven, the manufacturing process is refined, and the improved performance is not just a matter of opinion; it is a dynamometer measured matter of FACT! Fall in love with your car all over again - and may your next 100,000 miles be the best 100,000 miles of your life!"

Pulstar Pulse Plugs ef1i SET OF 8 IRIDIUM - Optimized for PERFORMANCE Review

Bought a set of 6 for my V6 2010 Chevy Camaro...It's been a week now since I installed them , @600km , and they work fine.
There is a slight difference in throttle response and acceleration , but nothing special.Yesterday I went to the race track and the engine ran strong without any hesitation at all.
Bottom line , they are better than my OEM spark plugs but a little pricey....about the fuel economy , I can't say anything because it's too early.
I would recommend them.
UPDATE :
After 1&1/2 years and over 30K on them I would say they work just fine.
Overall fuel economy went up with @5% since I installed them.
Throttle response is good,the engine starts every time the same,hot or cold.
