    Comments about Denso SKJ20CR-A8 Iridium Long Life Spark Plug:

    I wanted a Delco Iridium but was unavailable for this application, (Jeep V-6). These plugs worked fine but I have used the Delco's previously and prefer them.

      Great product for my MazdaSpeed Protege. It's gapped perfectly for turbo applications and has improved my car's performance immensely. I'll only buy these plugs when it comes time to replace again. Worth every penny!
