    How do you know when it is time to change your spark plugs. I have 89,000 miles on my truck and never have changed them. Is it time? or should they be fine?

    G.M. said they are good for 100k.For me I changed them at 70k,along with new Wires.It come down to how your truck is running,good,bad.I would said pull a couple of them and see how they Look.

    It seems a lil sluggish at times. But idk. It might be because its such a big engine and a heavy truck.

    Went was the last time you had the Throttle Body and injector's clean? That may be why your Truck is Sluggish.Thats just a Guess.

    Idk about the plugs bug if your gonna get wires I suggest the MSD wires

    Im gonna change my plugs and wires soon. I plan on going with Bosch +4 Platiums and MSD wires... it seems like a very popular pairing

    I am getting ready to change my spark plugs and wires on my S-10, and I just hit 50,000 miles on it. It is running like crap, so I figure it's time for a tune up. In the past when I have had injector problems on newer vehicles, it will get to a point where it will seem like you lose about 50-75 hp and it would almost cut out at an idle. Hopefully a tune up cures your problems, because once you get into the fuel system your talking some good money there. :neutral:

    i just put in some Bosch Platinum+2 plugs , and some standard autolite wires from a local advance auto store, the guy actually called around and compared prices to get me the best deal. i swear i'm probably getting twice the mileage now. i changed them at 95,000 i'm sure previous owner never changed em, they were burnt to a crisp.

    I've used those Bosch Platinum +2 plugs before, they worked well on my truck. It's probably not a bad idea with the E10.

    Throw some SeaFoam through your engine and it will clean out all the carbon buildup. Cleaning the MAF and throttle body is a good idea too. Change your oil, put in a new fuel filter then throw in some new plugs. You should be very happy with the newfound pep! :rules:
