    Just changed mine out today...

    Assumed that Car Max had changed them out before I bought it from them since it was sitting at 32k when I got her. Well, you know what they say about assuming. F*ckers had never been changed and I'm sitting at 67k miles as of the swap.

    All of the gaps were right around .6 and I felt an immediate difference after changing them out. Gonna have to hit the wife's 4runner soon as I get a training holiday. Got hers from Car Max as well (different location) and the mileage was about the same when purchased.

    Great write up. Helped me save a lot of (fiddle f*ckin') time.

    After 1500 straight highway miles, I was beginning to think my gaps were off a little after my recent plug change due to my mpg only being 19 highway (normally average 21)...my wife and I were sharing the driving and I woke up from a power-nap and figured out what the issue was...her lead foot and driving 85mph :rolleyes:

    Thanks for the how to Chris4X4! I did mine last month, using your guide. My 2005 only has about 27500, but it's been 8 years (Yeah, I only use my truck for trails and running errands). They were nice and hard to break loose, the gaps weren't off at all, but the electrodes were def. browned.

    While I was doing it, I also cleaned the MAF, the TB and my TRD air filter. AND flushed the brake fluid too! TB was really black and it took a half tank before the computer relearned everything. First tank of gas after all that was like 10 mpg, but now I'm back up to 16 (city driving).

    114,300 miles on mine and just changed for the first time. The gaps on the old ones were between .068 and .073. I gapped the new ones at .042. It feels smoother and quieter, but maybe it's just me

    My sons truck is a 2002 Tacoma SR5 Prerunner, he stuck it in a water- mud hole and drowned it out, after pulling out it wouldn't crank. His friends told him the starter was bad, after I went and got the truck I pulled the starter off and had it checked and it's fine, but after putting it back on it still does the same thing, makes a loud clank at the starter and flywheel, almost sounds like the flywheel is locked. the oil looks good, and suggestions would be greatly appreciated, thank you in advance...

    Changing the plugs because of the gap going out of spec is good, but better than that is, making it easier to take the plugs out when you do change them.

    Taking factory installed plugs after 100,000 miles could present a problem I would never want to deal with.

    I'm sorry but my brain is not processing "TB". All I can come up with is Turbo. Is that what you are talking about?:confused: Just wondering if there's something on my 2006 to which I haven't paid proper attention. I don't have a Turbo on it...:)

    If you've never cleaned yours, you'll be surprised what kind of crap is on there. I took mine off the housing, but left the hoses still hooked up, then sprayed the shit out of it with cleaner and used a ton of Q-Tips. If you do it at the same time you do the plugs, it's easier since you have the air intake mostly out of the way.

    Here you go my man....

    I'm at 76,000 miles and I've had the plugs sitting in my garage for so long. I'm going to finally change mine now too. I've always wondered what would happen to the truck if they never got changed. I figured it'd just start running poorly. I hope I can get a noticable change in performance.

    Great post I was wondering if this was difficult. The stealership wanted $110.00 to change my plugs. They told me the last 2 plugs were hard to get to.

    Just make sure you have a 15" extension or two extensions that you can double up. On driver's side bank, the front and rear are a bitch, but not impossible. Take your time, or if you have elf sized hands you should be GTG.

    Passenger side bank is a breeze.

    I finally replaced mine today at 76,000. The measurements of the worn plugs from back to front:
    Passenger side
    .055, .066, .054

    Driver side
    .071, .071, .071

    Pretty worn out. I hope I get some better fuel mileage. Thanks Chris!

    Worth pointing out that you don't have to remove the Surge Tank Stay or the Intake Hose (Just take off the intake filter housing).

    The lower bolt connecting my Surge Tank Stay was rusted on there really freakin' tight, so rather than risk shearing it I managed to get by just fine leaving all that in place. Sure wish the dealership/factory used antiseize when they put the plugs in - not pleasant to take them out without it.

    I'm debating on trying this. I'm for sure going to do my front/rear diff oil change and transfer case. I always changed the plugs in my 94 5.0 GT but this looks so much more complicated. All the clips and stuff to take off. That and the fact that I don't have a torque wrench never used one before either. I've always been good about not stripping bolts but this would be a more costly fix than a stripped oil drain plug. Any first timers with this modern stuff have any problems ??
