    Changing or removing Spark plugs & Coil packs

    I was tinkering with my intake the other day when I had it off in 30 seconds I figured I should get some anti seize on my spark plug threads for the remaining 96K miles they will be bolted down.


    Tools needed:

    3/8 ratchet
    6'' or equivalent 3/8 Extension
    5/8 deep socket
    10 MM socket
    Needle nose pliers (If you have a hard time getting the connectors off the coils like I did on one of them)
    Copper*** anti seize (Aluminum silver type is good stuff but I was taught in automotive training courses to use copper)
    dielectric grease (helpful and helps seal the coils)

    First remove the intake baffle, it can be taken apart in two pieces to make it a bit simpler.

    The first piece is the snorkel/breathing tube side, it is held in by (1) 10mm bolt close to the oil fill cap.

    Attachment 2519

    It should wiggle free of the air box with the bolt removed.

    Next the main air box, there is (2) 10MM bolts behind it that are somewhat difficult to see in the back.

    This picture shows one of them and how close it is to the firewall. Tip: if you put some dielectric grease in your 10MM socket it will most of the time hold your bolt as you pull your extension up and out. My hands barely fit but then again I have large hands and arms, I think most of you guys will have no trouble reaching around the air box between it and the firewall.

    Then the easy bolt that is on the left of the valve cover (red and green markings on all bolts.

    You can see it here to the right of the main air box inlet.

    Wiggle the breather hose off the clip built into the air box

    If you can't get enough slack to do this then wiggle the air box and lightly pull up to release it from the rubber bushing in the valve cover, then position it to get the breather hose off.

    Once this hose is off and you have wiggled it/twisted it, it should "pop" out of this rubber bushing.

    Next comes the easy parts, remove all the plug harnesses from the ignition coils (they are wired just right so they can't be mixed up). I try to avoid putting any kind of dielectric grease or other things on these terminals.

    Next remove the (3) 10 MM bolts holding the three coils in. (don't leave them in the coil, they will fall out)

    Carefully remove each coil keeping them in the order they were removed (they honestly don't have to be in the same order, I just prefer to keep them where they came from, same with the plugs)

    Use the 5/8 6'' extension 3'8 ratchet to break loose and loosen the spark plugs. When they turn by hand with the extension till they feel super loose you can use a coil pack to pick them up out of the head.

    They told me in the GM delco classes that copper anti seize should be used because it doesn't interfere with grounding of sensors/spark plugs ect.

    Oops too much anti seize, they'll be okay though.

    Its pretty harsh doing this but if you prefer not to there is other ways of putting the plugs back in the head besides dropping them in (that's what all the techs do) such as dielectric grease on your 3/8 socket to make it stick inside the socket slightly, or use a 3'8 rubber hose 6'' long to hand thread them back in. I use the dielectric grease method myself but honestly I've never seen a tech have a issue with just dropping them in the hole.

    I add a small amount of dielectric grease to the outer seal of the top of the coil pack.

    Once you have all of the spark plugs tight with the extension/hand, torque them to about 15-18 ft lbs. I learned this method a long time ago, when using a 3/8 ratchet grip it at the head and torque it tll it feels snug, I've checked before and usually get close to 15-16ft lbs, if your not confident please use a torque wrench.

    (here is a picture of my big hand and its placement on the ratchet)

    Once all your plugs are torqued, pop your coils back in by pushing them in and twisting them very lightly (1/16'' turns or less) just to get them seated onto the plug and to make a good seal with the head. Put the 10MM coil bolts back in each coil, reconnect the harnesses.

    Then get the air box (inspect the air filter if you haven't already) then line up the lower pin with the rubber grommet in the valve cover, it should push back into the bushing line up with the bolt holes.

    Put the rubber breather hose back into the air box holder, then re install the rear bolts, then the front bolt. Put the two front clips back on last, make sure the guide pins on the driver side of the front part of the air box go into the rear box before attaching the metal clips.

    Re install snorkel and 10MM bolt for it (it might take some wiggling to get into the air box).

    Very easy! just have patience and if you know your going to drop bolts have a magnet, flashlight, clean work area (to look for them under the car).

    Is that really the service interval??

    Definitely worth doing this so you know they'll come out easily later when you need to get 'em out.

    The service interval is 105k miles for iridium tipped plugs. I had never heard of iridium before so I looked it up. Its a member of the platinum family and the most corrosion resistant metal on earth

    Yes I believe your correct @ 105K service for the spark plugs. They are Iridium NGK plugs Part # 93298 . With every iridium plug I've seen they come pre gapped and you do not want to gap them if you don't have to (can crack/damage the indium coating).

    Most people won't need to do this if they are doing their valves themselves, they can wait for the 30K and pull them out then (makes the engine super easy to turn over...well at least it did for my aircooled volkwswagens... I can only imagine a 1.2 tripple). But if your doing the dealership valve adjustment approach you might want to do this (some techs just bump the engine over with the starter or he man the engine).


    I first searched the NGK Part # 93298 after I bought my Mirage and they were close to $12 a plug. I found them now on rock auto $18 for all 3 shipped to my door (with discount code).

    Hi, what's the ideal electrode gap?

    Iridium plugs come pre gaped in the package, they should not be touched.

    Most spark plug manufacturers apply a coating on the threads and no longer recommend anti-seize.

    Yup this is true, but I did not use the typical anti seize, I use copper anti seize that is sensor and spark plug safe, NGK says that but when I was drilling out broken spark plugs I wondered if anti seize would have helped haha. My Mirage plugs were pretty tight in there, not as tight as I would have wanted them for sure, NGK is very good about not seizing and this is likely why, I just wanted to be safe, when the first 5.4 fords came out nobody knew this would happen, a few of the owners that did this saved themselves from any worry. The copper anti seize has given no issues to my 3a92, just piece of mind

    Iridium spark plugs will run quite a while before they start having misfires. I see around the 'web where there are 200k vehicles running on the original Iridium spark plugs. But the performance degrades. I pulled out the factory Iridium plugs on my Focus at 36K miles and replaced them with some platinums. Gas mileage went up a bit and the power was definitely restored.

    Pulling them out to anti-size them is definitely a good idea.
