Diamond Fire Spark Plug for 07-11 Jeep Wrangler JK |E3.66

The advanced electrode creates a quicker pressure rise in the combustion chamber by exploding the air/ fuel charge more efficiently. The additional turbulence created in the chamber results in increased power output. More pressure on the piston equals more power at the crankshaft. Fuel consumption is reduced since more fuel is put to work on the piston. It's simple. More fuel is converted to work reducing un-burnt exhaust and hydrocarbon emissions. Fuel economy improves since less throttle is needed to produce the same amount of power. Less unburned fuel remains on the combustion chamber surfaces to reduce carbon and soot deposits and incrrease engine life. Fuel usage may be reduced by 3% to 13% depending on the engine and driving habits while power gains may reach 6% to 12% on average.
