    I just purchased a new oem set of spark plugs from my local Ford dealership. I have a 2012 mustang 3.7 V6. What is the correct spark plug gap. Thry cam pre set, but he said to re check as they could have gotten knocked around during shipping.

    You always check the gap before installing.

    .45 From the factroy.
    .35 - .38 if under boost.

    The cylinder firing order for the 3.7L Mustang is 1-2-3 on the passenger side
    and 4-5-6 on the drivers side. The firing order is 1-4-2-5-3-6.

    Since you have to remove it, clean the intake manifold/plenum.

    Got it, thank you. Oh, I didn’t know you had to take off the intake. Guess I’ll be watching a few videos.
