Comments about Autolite Double Platinum Spark Plug:
These were the original plugs in a Mercury Milan 2006 which had 91,000 miles on the plugs. In my opinion it is wise to use an original plug if the original plug has provided good service. Changing brands and type of plug can cause big problems. The price of these platinum plugs compared to other brands are very reasonably prices.

Comments about Autolite Double Platinum Spark Plug:
Made for Dakota is in ?. Opened the first one up checked gap and it was >.50 when Dakota is .40. When you spend [$] per plug you would think it would be gapped & if not somewhat close. So I checked 7 others & all were .50 or >. Spent more time bending/adjusting to make .4 than it took to change. Then I always worry what damage I did to the plug trying to get it gapped right. It was 830 so too late to take back & truck was already appart, so I cont.. Well truck started & ran..That about all I can say.

Installation Instructions: 1. Adjust the gap on the replacement spark plugs. At the tip of the spark plug that enters the cylinder head is a small metal piece shaped like a hood. The tip of the hook hovers just above a metal circle on the bottom of the spark plug. These two metal pieces are called the electrodes. The distance between these pieces is referred to as a “gap.” The gap determines the length of the spark when the spark plug fires. Before the new plugs can be installed, the gap must be adjusted to .035-inch with a feeler gauge. Select the blade of the feeler gauge which represents .035-inch, then insert the blade between the two metal pieces. Bend the hook-shaped piece toward the plug until the proper gap is reached. 2. Remove the spark plug wire for any one spark plug. There is no particular order by which the plugs must be replaced. However, it is important to replace only one spark plug at a time to avoid crossing the spark plug wires. Grasp the rubber base of the spark plug wire, where the wire connects to the spark plug, then firmly pull the wire off of the plug. Do not pull the actual spark plug wire, as the wire may pull out of its rubber base. If the wire is stubborn, twist the base of the wire before pulling it off of the spark plug. 3. Remove the spark plug with either a 10 or 13 mm spark plug socket, depending on the engine, attached to a socket wrench by turning the spark plug in a counterclockwise direction. 4. Insert a replacement spark plug into the cylinder head, then twist the plug into the cylinder head by hand until it cannot be twisted further with reasonable effort. Tighten the spark plug into the cylinder head with the spark plug socket by 1/4 of a turn. Take care not to over tighten the plug, which may cause the it to break. 5. Press the rubber base of the spark plug wire onto the top of the replacement spark plug until the wire clicks into place. Follow the same procedure for the remaining spark plugs.
