Comments about Autolite Iridium XP Spark Plug:

Installed these to replace the Autolite Double Platinum plugs that got me 70,000 mile of highway commuting to Denver. The Double Platinum gaps eroded from 0.040 to 0.067 in those 70,000 miles. I expect the same or better performance from these Iridium plugs. Noticed a better throttle response with the new plugs - but, that would be expected with new plugs. Note: be sure to check the gaps on the plugs from the box. I found a range of 0.035 to 0.046 in just my four (4) plugs.

    Comments about Autolite Iridium XP Spark Plug:

    I've tried regular, platinum and double platinum plugs in my Dodge cars and trucks. I did a little research looking for a plug that would give me crisp throttle response even when the vehicle was cold. These plugs accomplished that. They are all I've used for the last 15 years.

        Spark plugs easily installed. Performance and gas mileage increased, but mostly because old plugs were pretty worn.

                • Q:

                  Are these plugs pre-gapped? Since they are iridium I assume the are gapped to OE specification?

                    Well this all depends on the skill level of whoever is removing or replacing the part. Some may have a harder time than others who have experience. I would recommend purchasing a Haynes repair manual specifically for your vehicle. This should be able to assist you further into detail on how to repair or replace specific parts.
