Just a little FYI for you..From 4x4 wire:The factory installs different brands of spark plugs on each side of the 3.4L V6 engine. As near as I can recall, the more expensive NGK plugs are used on the passenger side of the engine, under the coil packs. If it makes it easier for you, it would be perfectly fine to use NGK plugs in all six cylinders. Generally, spark plugs are sold un-gapped, meaning that you would have to adjust the gap prior to installing. Both the NGK and Denso plugs specified in my Owner's Manual are sold pre-gapped at .044", which is close enough to the .043" requirement in the Manual.Talked to URD and I was told the plugs DO NOT come with the gapped, you need to gap them to .042
I tried to tell them but I guess my 20 years experience didn't matter..Thanks for that though..bringing this back to solidify what tacocrazy said about gapping bkr5ekb-11 spark plugs. they do not need to be gapped they come with a .44 gap from the factory. if you look at ngk's website they say the 11 = .44 gap
i know there were many misconceptions regarding this question.
Well, checking the gap for the plugs isnt bad advice. It takes all of five seconds per plug.I tried to tell them but I guess my 20 years experience didn't matter..Thanks for that though..
who's not checking the gap before installation? that should be a given with any plug before it gets installed.....Well, checking the gap for the plugs isnt bad advice. It takes all of five seconds per plug.
The sparkplugs in the package are supposed to have a cardboard sheath to limit them bouncing around inside the box during handling, but it doesnt always prevent it, and even though they are pregapped its a good idea to check the gap to make sure it hasnt closed a little bit.
Spark plugs are always designated in a specific service/replacemnt time interval, but it is my experience that they dont always NEED to be changed at that time. Its usually just preventative maintenance to replace them, especially because they are cheap, but if one so desired a simple cleaning and regapping could yeild a plug life probably three or four times that of the manufactuerers specified interval until they need to be changed due to wear on the electrode. Sparkplugs also last a helluva lot longer in a good running engine. Sparkplugs are your window into your engine, you can see how your combustion flows, your timing, mixture, arc etc by inspecting the plugs. A lot of guys dont know how to "read" their plugs and simply put them in and forget about them until its the specified interval to change. Id recomend pulling them every five to seven thousand miles to inspect and check the gap. I check mine about every other oil change.
As far as my recomendation on the plugs to use, use toyota. Not that the autolite specials wont work, they likely will be more than sufficient in a stock motor, but nickel and diming your engine components spending $1.29 per plug as opposed to $2.50 per plug isnt going to empty your wallet and its good piece of mind. Personally, I have been using some ngk iridums for quite sometime. I check the pluga and gap reigously and havent had to make any real adjustments in the nearly 20k miles Ive put on them. other than normal discoloration, there seems to be no noticable wear. They are considerably more expensive however.
