The V6 engine uses platinum resistor spark plugs. They have resistance values of 6,000 to 20,000 ohms when checked with at least a 1000 volt tester.Do not use an ohm meter to check the resistance of the spark plugs. This will give an inaccurate reading.Cleaning of the platinum plug may damage the platinum tip.Apply anti-seize compound to spark plug threads only at point (1).When the spark plug has a single or double platinum tip (2), a thin platinum pad may be welded to both, or just the center electrode end(s).

Extreme care (1) must be used to prevent spark plug cross-threading, mis-gapping and ceramic insulator damage during plug removal and installation.
