What is the correct OEM spark plug for 99
It seems every parts store I call claims a different OEM replacement sparkplug. I want to replace my old plugs with OEM AC/Delcos. Unfortunately, I cant read the number off any of my plugs. Must have been a batch with bad printing. So, what's the right part#?

A new spark plug has been released for use in the above vehicles. The new
spark plug has an Iridium tip instead of the current Platinum tip. Due to
the different tip design, the gap of the spark plug has also changed. The
new spark plug, P/N 12571164 with AC Delco P/N 41-985, is gapped to 1.01mm
(0.040 inches) when the spark plug is made. The spark plug gap is set
during manufacturing and should not be changed or damage to the spark plug
may result. Any new spark plug found to not be properly gapped should not
be used.
