Tenneco’s Powertrain business group is launching a range of industrial Champion spark plugs for the aftermarket which enable long life and increase service intervals for heavy-duty on- and off-road applications.
The newly-designed double Iridium M14 J-Gap high performance spark plugs with HEX16mm feature an advanced ceramic formula for improved electrical and mechanical strength. They are offered with two different nominal electrode gaps: 0.25mm for stationary usage with biogas and 0.40mm for natural gas commercial truck, bus and construction machinery applications.
A new ceramic formula for improved electrical and mechanical strength enables greater resistance against high-voltage failures. An Ni-plated shell hot-locking assembly increases mechanical robustness against dynamic combustion pressure. Further, the combination of laser-welded iridium pads and a tailored mass of precious metals provides lifetime improvements and service intervals over similar spark plug technologies.
