The Bosch 7305 Double Iridium Industrial Spark Plug was optimized for landfill and biogas applications looking for longer service life. The large, 2.4mm high content iridium center and ground electrode resist wear and erosion caused by biogas applications. Test results have shown over 4,500 hours on a CAT 3520 running landfill gas. This is 50% longer than the previous plug used. Longer run times reduce engine downtime. The result is reduced operating costs and higher revenue for the operator.
