Spark Plug: Description and Operation
SPARK PLUGS - PLATINUM
The 2.7, 3.2, and 3.5L engines use platinum resistor spark plugs. They have resistance values of 6000 to 20,000 ohms when checked with at least a 1000 volt tester. For spark plug identification and specifications, refer to Specifications.
Do not use an ohm meter to check the resistance of the spark plugs. This will give an inaccurate reading.
The spark plugs are double platinum and have a recommended service life of 100,000 miles for normal driving conditions per schedule A. The spark plugs have a recommended service life of 75,000 miles for severe driving conditions.
A thin platinum pad is welded to both or center electrode end(s) as shown. Extreme care must be used to prevent spark plug cross threading, mis-gaping and ceramic insulator damage during plug removal and installation.
CAUTION: Cleaning of the platinum plug may damage the platinum tip.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
