Champion Spark Plugs are designed for all marine applications, such as inboards - including diesel engines that require glow plugs - outboards, jet boats or personal watercraft (PWC). Champion's marine plugs are easy to remove and are particularly well-suited for saltwater environments.
Champion marine spark plugs also have a patented Mag Suppressor that provides maximum protection from radio frequency interference (RFI) in GPS/fish finders.
