Automotive Spark Plugs - E3.42
E3.42 is a 14mm, 0.460” reach plug with a taper seat. It fits domestic
applications in the 80’s to early 90’s and is widely stocked in
automotive retail stores. E3 automotive plugs have three legs securing
the DiamondFIRE electrode to the shell. This allows for excellent heat
transfer and helps to create more turbulence in the cylinder. The
patented DiamondFIRE side wire is proven to increase power, reduce fuel
consumption and improve hydrocarbon emissions in long-term use. The
unique ground electrode and full-size center electrode also provides
optimal performance for a guaranteed five years or 100,000 miles.
