Perfect fit for my 06 Dodge Ram. On my engine the gap required was .045, out of the box plugs were set at .040 which is not a big deal you should always check them anyway, set them correctly and she purrs like a kitten once again.

Although, I drive a lot paying for gas never affected me, until I noticed that I was filling up more regularly and then noticing some hesitation at stop lights, idling and also nearly stop running completely. So my buddy said " hey sounds like you need a time up" bought the Bosch pre gapped spark plugs, easily installed in less then an hour because I took my time by saving me money. So no more hesitation, stopping, and bad idling for me.
