How would IRIDIUM POWER compare against high-performance spark plugs offered by other spark plug manufacturers?
The following table gives examples of high performance plugs marketed by other companies.
The use of an iridium alloy for 0.4 mm diameter center electrode, a tapered cut, synonymous with high performance spark plugs, in the ground electrode, and DENSO's original U-groove, make IRIDIUM POWER spark plugs high performance spark plugs.
