Spark Plug Application Chart Update

For those interested, below is a revised spark plug application chart that shows the Mopar part number for the 1999-2001 4.0 spark plugs. The previous version of this chart showed Mopar part number 68304022AA as the part number for the 1999-2001 4.0. I've been informed by the dealer that Chrysler aborted that part number and have fallen back on their selection of the NGK ZFR5N plugs. See the Tech Tips info below. It also shows the ZFR5N plugs replacing the Champion RC12ECC plugs.

Revised chart:

Nice!! We should combine this with other Maintenance items like Air Filters, Oil Filters and make it a sticky.

That Tech Tips does prove that Chrysler recommends the NGK ZFR5N plugs over the Champion RC12ECC plugs.

We have proof. Vindication at last.
