E3 – DiamondFIRE Automotive Spark Plug: More Power, Saves Gas (Part No.E3.53)
from
$6.99
The Spark Plugs are the product of years of fundamental research in the combustion field. The unique patented electrode configuration of these new The spark plugs increases the amount of combustion pressure created during each power stroke of an engine, which results in a marked increase in power output, fuel economy, and reduced emissions in all gasoline engines. E3.53 is a 14mm, .708 reach plug with a taper seat. It fits domestic applications, and is widely available in automotive retail stores. The automotive plugs have three legs securing the Diamond Fire electrode to the shell. This allows for excellent heat transfer, and helps to create more turbulence in the cylinder.
