    Say what you want, don't cry when you get bitch slapped in real life, these forums are moderated by your make believe friends of your alter (troll) ego.
    My opinions lean toward research and what past experience has shown.

    Most of the time what designers use has already been used in different applications.

    The stock spark plugs are plated and they need not to be coated with anti- seize grease because depending on the type you use the torque specifications are changed (reduced) yet I have found that the only time I have had a spark plug backout has been when using anti-seize.

    Effectively NGK does not want you to use ant-seize on their plated spark plug threads.

    I would recomend checking the torque settings of your spark plugs before a long trip or if you have used any type of lubricant on the threads when installing them.

    Some of my friends are engine performance buffs (gearheads) and everyone at one time or another brings up the ignition subject, hotter plugs or, colder plugs, design variances, wire sizes, timing, sensors, computers, etc...

    With spark plugs there are several determining factors surounding design and applications but they follow a few basic guide lines that should be considered.

    Combustion chamber design.
    Engine compression ratios.
    Fuel octane
    Driving habits.
    I use the phrase "driving habits" in a broad sense; to cover where and how you drive, and that includes traffic and terrain.

    With Toyota the Japanese business ethic doesn't compete domestically but internationally and abroad.
    It is nothing new for them to obey restictive emmision laws and follow another countries regulations because Japan's own laws have been shown to be demanding in compliance.

    The spark plugs that come in their vehicles are in compliance to fulfill
    regulation testing standards and warranty standards, and the brands that are used also cover the regulations for fair economic practice laws set in place by their country.

    Anytime an ignition component is changed from what is common design in a vehicle, the ECM to recognise the change should be reset if it is desirable to expedite the behavior and adaptation process. (disconnect the negative battery cable from the terminal for 3 to 5 seconds)
    It then takes appoximately 50 miles of drive time for the ECM to adjust efficently.

    One of the steps that is outlined when either testing or replacing
    electrical and ignition components is to disconnent to battery for the duration of the job performed.

    Touching the negative cable to a common ground for a few seconds after disconnection from the battery also helps capacitive discharging of the system.

    One of the reasons spark plugs don't last longer than we wish they would is because they loose their efficentcy from wear on the electrode edeges from the stress of the electrical currents ability to jump from the center electrode to the side electrode and the right angles that are manufactured into the plugs design.

    Through the convection of heat by compression in the combustion chamber and the rapid cooling from the air fuel mixture over repeditive cycles, the plugs litterally loose their edge.

    When the electrodes designed efficentcy is compromissed the electric current has a natural tendancy to find the path of least resistance in order for the current to travel to it's polar end.

    The current when facing resistance finds other points of collection to travel to and the direction of the spark developed can retard the combustion cycle and cause an incomplete burn and build carbon deposits which the carbon itself can retain heat and prematurely ignite the fuel mix causing pre-ignition/knock which further retards the ignition sytem causing fuel to be wasted in a effort to correct itself by restricting the spark plug from firing, cooling the affected chamber .

    Might want to make sure that you wrote that correctly. If you disconnect the negative cable from the battery, and touch it to a common ground location, you accomplish nothing. To discharge the on-board capacitors you need to disconnect the negative cable and connect it to a +12V point, which will discharge the capacitors. I assume that is what you meant to say.

    Wow. Um, wasn't following anything. Just saw a post in a forum that I was in already. You should be less paranoid? I am trying to make sure people know the CORRECT information and procedure before they damage something.

    Look arguing with you is a lost cause this should be taken to private messages but I seriously doubt you know how to respond to one.

    I don't want to be as large an orifice as your seeming to be, but I would like to point out that some one that has completed ASE training has proven at the very least that they have acomplished the task of reading and comprehension, to which you have failed at both.

    The positive aspect of your nature is that you will be undoubtedly be here more time that myself to give assistance to people that may really need it.

    But if you continue with the premmise of of being of the highest order of learning with nothing left to achive (a basic know it all) you not only do yourself a miscredit but all the people that have and use ASE as credentials.

    ASE even makes an effort to educate student in the ability to deal in customer service aspect of the work place.

    So either you had someone else take the tests for you, inherited them from your father that has the same name or, it was a long time ago or you haven't renewed your license since 1985 when you were 16.
    And although you may have known a lot back then things have changed,
    and obviously your memory isn't what it use to be.

    Every time you want to give the correct information what you are actually saying is you want someone to teach you because you don't know.
    Your challenges have been baseless and rudimentary.

    So son, please read more and post less , unless you have a legitimate question that isn't full of contempt and sarcasm.

    What I want is an applogy and or you to back down and get off your high horse or else you are going on my ignore list.( or at least this is what you could hope for)

    Well it seems that I am being called out. Well I have no problems at all with my knowledge, and my certifications. I will post in this, and the other thread our interesting PM that you initiated, and let us see which one of us has the proper qualifications.

    The following is a copy of the PM, and my reply. I decided to leave the spelling mistakes since it appears you, Lagunito, are saying I need to brush up on my reading skills. I think YOU need to brush up on your spelling skills.

    Feel free to post my quoted reply Mr Lagunito. You are barking up the wrong tree if you think I am not a qualified technician. I have tried to be polite and civil, but you sir, have fired the first shot. The gloves are now off. You WILL loose this battle.

    I haven't read thru everything on here about spark plugs but why does a GM engine go 100,000 miles between plug changes and the Tacoma only 30,000 miles? I have a 2004 GMC Z71 and had the plugs changed at 100,000 miles as recommended by the manufacture. I had no issues before or after, same gas mileage.

    There are numerous vehicles who have varying recommended mileage intervals for their spark plugs. Why is one different than the other? Well in the case of GM, they use only ACDelco plugs, and ACDelco says their plugs will last 100k miles when used in GM vehicles. Those are the plugs I have seen the most to be honest. I have used NGKs on all of the Nissan and Toyota vehicles I have ever owned.

    If you go to the NGK spark plug website, you can find this answer in their FAQ on how often to replace spark plugs.



    By the way, to be fair, and give you a chance Lagunito, I have also posted here:

    NO!

    Attach the BLACK lead of some jumper cables to the ground connector, and the other end of the BLACK lead to a copper water pipe, ground rod, or some other earthed contact. At the same time, connect a RED lead to the front tow hook, and the other RED lead to the hitch receiver. If you don't have a hitch receiver, you can try attaching to the driver's side rear spring shackle, but I make no promises. BTW, this only works with a stock suspension.
