E3 Toyota Tundra Spark Plugs 00-05

Introducing the E3 Spark plug. An entirely new type of plug that is proven to give dramatic results: increased horsepower, extended engine life, and improved fuel economy.

Burn Faster

E3's patented DiamondFIRE™ technology has been proven to be the most powerful way to ignite the air/fuel mixture for the most efficient combustion, and longest performance life. Until now, Spark Plug technology hasn't changed much from the original 1903 Patent for the flat "J-Wire" electrode that you see on most plugs.

More Power

Increases engine power  up to 12%. Thanks in part to the DiamondFIRE™ design, E3 Spark Plugs provide your engine with a more thorough, complete combustion resulting in better fuel economy as well. Reducing fuel consumption up to 13%, this is an investment that will pay for itself!

5 Year/100,000 Mile Warranty

Because of the cleaner, more thorough combustion, harmful toxic emissions resulting from unused and unburned fuel are reduced by as much 58%. E3 Spark Plugs reduce carbon deposits and material degradation inside your engine, extending engine life and promoting like-new performance. All E3 Spark Plugs are warranted against fouling, wear, and defects in materials and workmanship for 5 years or 100,000 miles.
