        This item is not a direct replacement as the website stipulates. Only copper plugs are a direct replacement for Hemi engines. Ask Chrysler.

            AAP did not have the AC Delco plugs for a Trailblazer and these were the cross referenced plugs. They seem too be well made. They only have a few hundred miles on them, so we will see how they hold up. They did restore power and mileage that had been lost.

                Hi Wayne, glad to assist you! This spark plug would be an exact fit for your 2001 Chrysler PT Cruiser. This is designed to withstand firing in both directions. Maintains optimal performance longer. OE/DIS approved. This plug is pre-gapped to 0.040".

            • Q:

              Oem states 0.044" gap. These plugs come with a 0.060" gap. Does the gap need to be adjusted.

                Hi Jim, great question! It is always recommended to gap the spark plug according to the manufacturer's specifications.
