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.

Their system showed incorrect plugs. The salesman siad they were right until I showed him original plug. They also said that it is not a 14mm 12 point socket for the factory plugs. Also showed them wrong again. Must say that the correct plugs work fine. Especially after having the defective coil, purchased here also, was replaced.

Comments about Autolite Iridium XP Spark Plug:

Provided a noticeable difference in performance. Granted, the old plugs were over due.
I believe the slight difference in price is worth the upgrade to the Iridium. I did not need any high performance plugs but also do not want to change out plugs every other year.
Vehicle called for 0.040 gap, these plugs came set at 0.042 (+- 0.001). They were consistent, so I chose to use them as is.

Advance Auto Parts does sell Made in the USA products as well as products manufactured from many other countries in order to keep our pricing competitive.

          • Q:

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

              A:

              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.
