11-25 Ram /  Durango / Jeep Grand Cherokee 3.6L V6

E3.82

The E3.82 Automotive Spark Plug is precision-engineered for engine vehicle. Designed to exceed OEM performance, the E3.82 utilizes a patented DiamondFIRE electrode to deliver a stronger, more efficient spark that improves combustion, increases power, enhances throttle response, and reduces emissions. This plug features a 12mm thread diameter, 1.000” thread reach, and a gasket seat, making it ideal for a wide range of late-model domestic and import applications. The dual-leg electrode design ensures excellent heat dissipation and cylinder turbulence, which promotes a more complete air-fuel burn and contributes to long-term fuel savings and engine health.

High-Performance Electrode Design:

• DiamondFIRE side wire with two-leg support enhances combustion, improves power, and reduces emissions.

Improved Engine Efficiency:

• Increases horsepower
• Enhances throttle response
• Lowers hydrocarbon emissions
• Improves fuel economy over time

Durable Construction:

• Thread Diameter: 12mm
• Thread Reach: 1.000"
• Seat Type: Gasket
• Hex Size: 5/8"
• Gap: Fixed (non-adjustable DiamondFIRE tip)
• Type: Resistor

E3 Spark Plugs uses its patented DiamondFIRE design to target efficient combustion and consistent ignition performance across automotive and racing applications. For performance builds, a quality spark plug choice can support clean burn characteristics and reliability—especially when tuning for higher cylinder pressures or more demanding driving conditions.
