Proper Plug Gap

[auroralover]

Taking my 97 in tomorrow for new plugs and wires and a tranny drain and filter (87000 miles). What is the proper gap for the AC Delco Platinum plugs for the 4.0?
Is it .65 or .50? I believe there are conflicting settings on these, according to what I've read on other boards. Just want to make sure all is right

I have seen both .60 and .50. I was told by autozone that they should be gapped at .60. I think Peter mentioned that .50 was correct.

To make a long story short, I guess I can't help you.

Sorry

The most correct information will be found under your hood. The vehicle emissions information sticker will list the appropriate plug gap.

i'm pretty sure i've been gappin' mine at .050, which is what the thing said for mine.
