The result of independent research and testing suggests that using E3 car spark plugs in your vehicle can increase horsepower when compared to more conventional spark plugs. Our patented Edge-to-Edge ground electrode outperformed other plug designs, including premium spark plugs offered by the major manufacturers.

After installing the E3′s I noticed the idle smoothed out and the truck is running better. Gas mileage has went up 1 mpg. Well worth the price.” “These Spark Plugs really work!

By simply replacing your existing plugs with premium E3 spark plugs, your ride will have the performance it deserves. Horsepower gains of 4-6% can be expected, depending on engine class size.

5 years How often you change the spark plugs in your vehicle depends upon the type of plugs you use and how you drive the vehicle. Naturally, better plugs and easy driving conditions are optimal. E3 automotive spark plugs offer a 100K mile warranty, or 5 years from the date of purchase.

Platinum spark plugs These plugs are a high value for the money, giving you considerably higher performance, gas mileage, and longevity that's second only to iridium plugs. They can last about twice as long as their copper counterparts, making them a popular choice in city cars and some sports cars.

Tailored for high hp boosted (turbo, nitrous or supercharged) applications, the plug features E3's patented diamond-shaped ground electrode for maximum combustion and edge-to-edge spark, as well as a resistor to keep stock electronics functional. The E3.

Increased Fuel Economy – Misfiring spark plugs can reduce fuel efficiency by as much as 30%. New plugs that are replaced at regular intervals maximize fuel economy, saving you money. Smooth, Dynamic Starts – Convulsing starts will be a thing of the past when new spark plugs are installed in your vehicle.

50,000 kilometres Most manufacturers recommend replacing spark plugs every 50,000 kilometres, but spark plug quality varies. Some last around 130,000 kilometres, while cheap plugs made of copper may last approximately 40,000 kilometres. “Extended life” spark plugs made of more resilient metals can last up to 160,000 kilometres.

Smooth, Dynamic Starts – Convulsing starts will be a thing of the past when new spark plugs are installed in your vehicle.

Engines powered by LNG and CNG should follow these guidelines. Use Iridium finewire spark plugs for best durability.

Any spark plug material should work well on a supercharged vehicle. The key difference comes with copper plugs, which will wear faster and must be changed out more frequently. On the other hand, platinum and iridium spark plugs were designed to go much longer without a change, so consider these materials first.
