The Spark Plug GAP Expansion Tool is designed to gently widen the spark gap on massive-electrode aviation spark plugs. Its hooked working end is used beneath the outer electrode, allowing controlled downward pressure to expand the gap without contacting the centre electrode.

This approach helps avoid placing force on the centre electrode and its ceramic insulator during gap adjustment.

  • Manufacturer part number: ATS483
  • For expanding the gap on massive-electrode aviation spark plugs
  • Nickel-cadmium plated tool-steel construction
  • Approximate length: 14 cm
  • Approximate diameter: 10 mm

Overview

This tools expands the spark gap of any massive electrode aviation plug safely and efficently -- with the key word being safely... In the past when you over-gapped a plug, and wanted to expand it back out, you would resort to using a screwdriver, dental pick, or whatever else was on hand. But this was almost a sure way to do damage to the plug. Because you would invariably push the screwdriver between the electrodes, which would cause pressure to the center electrode and risk cracking its ceramic casing. The end result would be either reduced performance or total spark plug failure. Not so with this tool.

Specifications

  • 5.6" long, .375" diameter.
  • Made of Nickel-Cadmium plated tool steel in the USA.

Instructions

  • To use this tool, simply hook it under the outer electrode and apply a bit of downward pressure to gently and safely expand the gap without any contact to the center electrode.
