1 - APPLY ANTI-SEIZE COMPOUND HERE ONLY

2 - PLATINUM SPARK SURFACE

The spark plugs are:

mounted below each coil-on-plug assembly
Platinum/iridium (dual precious metal)
long-life service of 100, 000 miles
accessed by:
- removing the coil-on-plug on the right bank
- removing the upper intake manifold assembly to access and remove the coil-on-plug on the left bank.

The spark plugs have resistance values of 3, 000 to 16, 000 ohms when checked with at least a 1000 volt tester. For spark plug identification and specifications. Refer to TECHNICAL SPECIFICATIONS .

Do not use an ohm meter to check the resistance of the spark plugs. This will give an inaccurate reading.

A thin platinum pad (2) is welded to both or just the center iridium alloy electrode end(s). Extreme care must be used to prevent spark plug cross threading, incorrect gapping and ceramic insulator damage during plug removal and installation.

Mopar® Nickel-Graphite Anti-Seize compound is applied to the thread area (1) to prevent damage to the spark plug during removal and installation.
