New CetraTM Spark Plug Leads have a non-metallic internal shield that permits use of timing lights, oscilloscopes, and other monitoring devices.
Monitoring engine performance is faster and easier, resulting in reduced downtime and improved operating efficiency.
SAFER-Multi-Fault Protection: Two independent insulation layers must be breached for a spark to occur. An internal conductive shield provides a safety path to ground.
May be used with BG All Weather Extensions.
May be used with unshielded spark plugs when used with BG’s CETRATM Series Extensions.
