Style Name: Iridium XP Verified Purchase
I purchased these spark plugs based on the picture. It shows two boxes. One large and one small. If you enlarge the picture you can read on the bottom corner of the large box, Cont. 4 plugs. In the description of the item, it said pack of 1. I thought the price was great and I needed six plugs for my vehicle so I ordered what I thought was 2 packs of 4. When I received my order today, all that I got were 2 individual spark plugs. I hope that Amazon corrects this soon so other people ordering the spark plugs, expecting 4 in the package, and only getting 1, won't be disappointed like I was. I rated this three stars not because of the Autolite spark plugs, but because of the misleading information.
