I dont have but I been looking for the spark plug data for a while, the oem is the bosch 4 ground tip one with do not gap. I got the ngk iridium and gap on it is .043" gap #1208. For your year, off the NGK site, its 6418.

Some other people have used iridium without any issues. I doubt there are any issues.. ill be putting mine in after I finish up the baby room in the house..
