spark plugs

i am going change my spark plugs. i have been looking at those 2 and 4 prong ones. what are the pros and cons of each?? or should i just stick with the one prong one?
i have a 99 taco with a 3.4l v6, .4x4

those are mostly just gimmick, i would stick with the factory Denso plugs

like joe said they are most a rip off! stick with denso! red oh yeah make sure they are gapped right or you will make the truck run like shit!

thanks for the help guys, like i said i am kinda new to the whole working on my own truck thing, so every little bit helps thanks again

Nick, I just changed mine, and I put the 1 prong ones in, and the truck did run like S@#T, so I changed them to the two prong ones, truck ran much smoother, I'd match what ever is in your truck.

Word to the wise, make sure you have a long extension when changing the plugs, and I'd change the wires at the same time. I used one of the old wires to pull the plugs out once I got it loose, and I also used the same wire to set the new plugs down in the holes. I cut the wire pretty short, and used it to set the plug in, and gave it a short turn, be sure not to cut the wire too short (the little metal connector will come out). Also, replace the tabs that come with the wires.

It took me a little time, never changed them myself, and the book wasn't really good with descriptions. Had them changed at 60,000, by the dealer and now I decided to save some money at 140,000. Good Luck

thanks,
i am going to have my roomate help me, it looks like it will take a little longer this time, of course it is my first time doing it. it is kinda funny but i had a hard time locating all of them (ha ha ha) you are right about the book not too clear i guess tha tis what you get when you are trying to explain 4 differnent trucks. I think i got it down alright though. by the way i decided to go with the 2 prong plugs, although i think i am going to take them back and break down and buy the denso's from the dealer. again thanks for all the help

Hey, if you run into problems, don't hesitate to ask, several of the guys on this forum have talked about changing plugs.

changing spark plugs is like changing your underwear. sooner or later you got to do it

if im not mistaken the 2 prong denso's are the proper plug for the 3.4

I used the 2 prong NGK's
