Crossfire V6-3.2L VIN L (2004)
Spark Plug: Description and Operation
The engine uses platinum tip resistor spark plugs. They have resistance values of 6,000 to 20,000 ohms when checked with at least a 1000 volt tester.
For spark plug identification and specifications, Do not use an ohm meter to check the resistance of the spark plugs. This will give an inaccurate
reading.
Spark plugs using either a single or double platinum tips have a recommended service life of 100,000 miles for normal driving conditions per schedule A
in this manual. 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
just the center electrode (2) end(s). Extreme care must be used to prevent spark plug cross threading, mis-gapping and ceramic insulator damage during
plug removal and installation.
CAUTION: Cleaning of the platinum plug may damage the platinum tip.
Remove the spark plugs and examine them for burned electrodes and fouled, cracked or broken porcelain insulators. Keep the spark plugs arranged in
the order in which they were removed from the engine. An isolated spark plug displaying an abnormal condition indicates that a problem exists in the
corresponding cylinder.
Spark plugs that have low mileage may be cleaned and reused if not otherwise defective. Adjust the gap between the electrodes to 1.00 mm (0.039 in.).
Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in a change in the spark plug gap or damage to the
cylinder head. Tighten the spark plugs to 28 Nm (21 ft. lbs.).
