    Hey there, Tundra Fam! I did a couple quick searches for Spark-Plug replacements for 3rd Gen Tundra's and didn't find anything. I figured I would share a few tips and photo's from tonights experience for anyone that wants to look over the process prior to poppin' the hood!

    Aside from the 8 Bosch Iridium plugs I bought from Amazon, I had the required tools on hand..
    Gather the following:
    • 3/8" Ratchet
    • 6" Extension
    • (2) 3" Extensions
    • 10mm socket
    • 3/8" swivel
    • Spark Plug Socket
    Once you've got your gear, pop your hood and add some odd-colored light!


    First - Remove the plastic "5.7L V8" cover. It should just lift straight up with minimal force.

    Disconnect your positive battery terminal as well... (10mm)
    843313EE-1990-44C4-8F44-FFF7A49EC6B3.jpg


    If we start with the passenger side, you're going to want to remove the air intake completely in order to make some room to work. This involves a couple of hoses, an electrical connector, and the short use of your trusty 10mm socket to loosen a clamp.

    First, loosen this clamp with your 10mm socket so you can disconnect the air intake.2A03DDC4-DA7F-493E-814D-16EE127A334F.jpg

    Next, remove both of these two rubber hoses...

    Finally, disconnect this electrical connector in order to remove your intake manifold and set aside...
    E2292682-160F-4231-B95A-F3ADC30474C1.jpg

    Next, you're going to use your 10mm socket and some varying combination of your extensions and swivels in order to remove the coil packs. (Photo's are an example of one of the coil packs, located on the drivers side.)
    E07DF5A3-F78F-4050-B627-9C157197C2EA.jpg 301F50EB-50F1-4EDD-9861-93A7F1A977B0.jpg C08164EE-842B-46CC-BF43-9F01FBCB39A9.jpg F0C1FF63-328B-42E8-9C56-C69985A24CE7.jpg
    At this point you can insert your Spark Plug socket and 6" worth of extension in and remove the existing plug. Replace each plug as you go, tighten, and re-assemble coil pack.

    **On the plugs on the drivers side of the engine, I used two 3" extensions, inserting the first extension and the plug socket half-way, and then attaching the second 3" extension in order to avoid removing various other engine compartment components. Just my suggestion - do what works well for you!**

    0E1F0C03-1A8D-415B-90E9-EB0B08876A15.jpg
    Continue to replace each plug and re-assemble anything you removed in the process. There really weren't any plugs that were significantly more difficult to remove than others.

    ...& now you should be done!

    Great write up! Out of curiosity how many miles are on your truck and how did the plugs look?

    Thanks @Blueknights75
    Truck has 82000 miles on it. Here's a photo of two of the plugs..

    Nice write up. Gearwrench magnetic swivel spark plug socket might make this job a little easier

    I'll be doing these this weekend. I went with NGK's new Ruthenium HX plugs which are suppose to be a better choice over Iridium. I shall see...

    I also sit at 82k miles

    Esteemed gentlemen of the sparks, I'm putting this plan together for my '15 5.7l as well and want to know recommendations for best plugs to use for this job. Note that I do not mind spending extra on increased quality or performance. I have 8 x Bosch 9613 Double Iridium plugs in my cart currently.

    Should I consider an improved coil while I'm at it or no sense?

    Thanks!

    HOUSTON WE HAVE A PROBLEM. "Disconnect your positive battery terminal as well... (10mm)"

    Conventional Flow vs Electron Flow
    https://www.youtube.com/watch?v=gQEuliFx_Pc
    https://www.youtube.com/watch?v=8Posj4WMo0o&t=127s
    https://www.youtube.com/watch?v=QV6zFhc4c00

    You never disconnect the POSITIVE (+ RED) side of a car battery first.
    If you only disconnect the positive side only it is not safe to work on. power is still on
    Always disconnect the NEGATIVE (- BLACK) side first and re-connect it last.
    Once the Negative side is disconnected it is safe to work on. Even with the positive side still connected.
    No need to disconnect the positive side unless you are removing the battery.
    Direct Current (D/C power) Electrons flow from negative to positive.
    The CURRENT is coming out of the NEGATIVE post and returns to the battery into the POSITIVE post to complete the Circuit (Circle)
    Why you ask. If you disconnect the positive side first and your wrench touches any metal part (AKA GROUND) as you turn the wrench it will put 700 AMPS into the form of a arch (spark).
    That is why you have a rubber/plastic boot on the positive side and not the negative side.
