    Just go to your local Ford dealer and they will get you the correct spark plugs.

    No. The only time you would need a colder spark plug would be if you had a power adder like a supercharger or turbo.

    Here's a link directly to the spark plugs section at rockauto.com

    Motorcraft Platinum plugs for $2.52 each is a good price. I'd just stick with them.

    No, you won't need different plugs for a 93 octane tune.

    These are most of the plugs available for the Marauder:

    Spark Plugs:
    Stock Heat Range:

    Autolite –104
    Autolite Double Platinum – APP104
    Autolite Iridium / Xtreme Performance – XP104
    Champion Copper Plus – RS12YC
    Champion Platinum Power – 3401
    Champion Double Platinum – 7963
    Champion Iridium – 9204
    Bosch – BSH7571
    Bosch Platinum – BSH4205
    Bosch Platinum+2 – BSH4305
    Bosch Platinum+4 – BSH4458
    MOTORCRAFT SP433 {#AGSF32WM, AGSF32WMF4}
    NGK V Power – TR55
    NGK G Power Platinum – TR55GP
    NGK Laser Platinum – PTR5C-13
    NGK Irdium IX – TR55IX
    AC Delco – R42LTS6
    AC Delco Platinum – 41810

    Colder Heat Range:
    NGK – TR6 (+1 colder)
    Autolite Iridium / Xtreme Performance – XP103 (+1 colder)

    NOTE: Personally I'd never run Champion plugs in any Ford product. I included the information for completeness.

    NOTE 2: Running colder heat range plugs won't do anything unless your tune is made for the colder plugs.

    NOTE 3: I change plugs once a year regardless of mileage. Cheap insurance.

    I put a set of E3 spark plug in my Mercury Marauder. And I love them. They work awesome for me. But everybody has different preferences. But these are worth every penny you pay for them.

    Looking at the online reviews of the E3 plugs, some like them some don't.

    Let's think about this.... if you'll get better gas mileage out of these plugs why wouldn't the car manufacturers use them since all of them want to get better gas mileage?

    Same with additives, if they worked the manufacturer would specify them in the owners manual.

    Glad they work for you!

    When they fail check here:

    2nd plug question in as many days.. With FastBlackMerc's part list, perhaps THIS thread should be a sticky?
