Designed for accurate spark plug electrode gap adjustments. Compatible with common 10mm, 12mm, 14mm, and 16mm spark plugs.
CNC Aluminum Construction
Made from durable CNC-machined aluminum alloy with a smooth polished finish and a protective red or black coating.
Reliable, Consistent Results
Helps achieve the desired electrode gap for proper spark plug setup. Some electrodes may spring back slightly after adjustment. For a target gap of 0.44mm, an initial setting of 0.42mm may help compensate.
Wide Compatibility
Suitable for many common spark plug brands, including NGK, Bosch, Denso, Autolite, ACDelco, and E3, subject to plug design.
Package Includes
