E3 Spark Plugs E3.31 Yamaha 1984-2009
This flame front ignites the bulk air/fuel mixture faster, moves heat into the combustion chamber faster and creates a more localized pressure front for faster pressure rise during the cylinder power stroke. The result is more complete combustion and an improvement in engine performance. A truly premium performance plug.

- E3.31 is a 14mm, 0.750″ reach plug with a gasket seat
- It is used in a variety of powersport applications, especially in snowmobile and Personal watercraft
- The patented DiamondFIRE ground electrode is secured to the shell with two legs to help facilitate heat transfer, and to withstand the intense vibration of powersport engine applications
- The unique DiamondFIRE side wire is proven to increase power, reduce fuel consumption and improve hydrocarbon emissions in long-term use
- The E3 ground electrode and full-size center electrode also provides optimal performance over an extended product life
