REVIEWS
Long Life Double Iridium-Rhodium technology acquired from natural gas industrial engines.
Iridium-Rhodium alloy 0.8mm center electrode surface exceeds OEM 0.7mm center electrode by 30%.
Higher Iridium-Rhodium alloy melting points reduce incidents of alloy melting/bridging the gap, misfires.
Fired In Suppressor Seal FISS resistor in reliable & durable, superior to the OEM Monolithic resistor.
Methyl vinil silicone rubber boots rating 500°F/ 260°C and stronger dielectric properties exceed OEM.
DuPont® Krytox 205 dielectric grease pre-applied to boots meet OEM requirements, fleet time saver.
90 day warranty for manufacture's defects and materials.
