WIDE RANGE SPARK PLUGS WITH EXTENDED REPLACEMENT INTERVAL
Wide range spark plugs with extended replacement intervals.
Replacement interval: see the table below.
Two or three ground electrodes, or special design spark gap and electrodes (
DOX15LE-1), which makes it possible to extend the replacement interval up
to 60,000 km. Centre electrode with copper core and higher thermal
conductivity ensures perfect function in all engine operating conditions.
Some types allow alternative discharge from the combustion deposits
on the insulator tip.
