The Spark Plug Tip Insert provides a reliable solution for avoiding spark plug malfunctions and engine damage caused by dislodged electrodes. These inserts easily replace the existing terminals on the plugs and can be reused; simply remove them from the old plugs and install them in the new ones.
These are designed for the NGK R6061 plug. We cannot verify that it fits any other NGK plug or if any other plug has an issue with the center electrode becoming dislodged. With that said, if you are running anything other than the 6061 plug you most likely do not need the insert fix. Sold individually, services one spark plug.
