Hot type plug: Available only for customers who often drive their car at very low speed which causes the plugs to foul easily.

## Plug Gap Inspection

  Caution

  • To avoid possible damage to the tip, do not adjust the plug gap.
  • To prevent damaging the tip, use wire type plug gap gauge when inspecting the plug gap.

1. Measure the spark plug gap using the wire type plug gap gauge.

  • If it is more than the maximum specification, replace the spark plug.

  Standard plug gap
  Australian specs.: 1.15-1.25 mm {0.046-0.049 in}
  European (L.H.D. U.K.) specs.: 1.05-1.15 mm {0.041-0.045 in}
  Maximum plug gap
  Leading side: 1.5 mm {0.059 in}
  Trailing side: 1.4 mm {0.055 in}

## Cleaning

  Caution

  • To avoid possible damage to the tip, do not use a wire brush to clean the plug.

  Note

  • To avoid possible damage to the tip, use gasoline to clean the spark plugs after removing dirt.

## Visual inspection

1. Inspect the following items:

  • If there is any malfunction, replace the spark plug.

  - Insulator breakage
  - Worn electrode
  - Damaged gasket
  - Badly burned insulator (sparking side)

## Resistance Inspection

1. Measure the resistance of the spark plug using a tester as shown in the figure.

  • If not within the specification, replace the spark plug.

  Resistance
  3.0-7.5 kilohms [25°C {77 °F}]
