Non iridiums resitor types: from sparkplugs.com
Heat range 7 - BR7EFS - stock number 1094 - gap 0.027"
Heat range 8 - R5724-8 - stock number 7317 - gap 0.019"
these are 14mm thread, 17.55mm (0.691inch reach), 5/8" hex, tapered seat
These would work for my 98 sunfire. Verify reach or length. Always compare to your stock plug to make sure it's not too long.
