spark plug settings?

[jayreiten]

i changed my spark plugs and feel my truck is running worse. i was told .32 is the gap i need on the plug. that apears to be twice that of the gap in my old plugs. any one know if that is the right setting or not?

Somtimes its a good idea to check the FAQ.
There is a lot of good info in there.
here is the link you need

What plug did you install? not sure which model truck you have since you did not tell anyone, but seems 0.031 is common gap on all engines except 93 v6 3.0 and they are 0.041 and the 96 3.4 are 0.043 but all the others from 89-96 are 0.031 on the gap!! http://www.toyotaownersonline.com/pu...arkplugs06.pdf maybe this will help maybe not? give it a try!! just do not run german spark blugs in you japanese motor ie BOSCH and make sure you use anti-sleeze!! and a torque wrench would be nice also!! ps most Toyota plugs come pre gaped!! hehe!!

here, ill post this in plain view. all this information is from NGK.
HogWild you are right, the bosch super plugs should not be used in anything other than german cars.
and never should any platinum plug ever be installed in a 22RE or 3.0

Hey thats great info!! So why do ya not wanta use a Platnum plug in the V6 3.0? they show a group of listings for applications of platnum plugs for these engines? 2 different metals? i suppose and chancing a broken plug?

[WristPin]

because the platinum plug is desinged to be ignited backwards from a normal plug. the spark will jump from the ground to the conductor.

and when used in a application that requires standard plugs, there is more resistinace on the plug, and the secondary igniton circut has to work harder.

was reading about torque applications on spark plugs and they said if ya lube them cut torque values in half?? so is anti sleeze a lubricant? suppose so!! please help me with your previous post , me being from arkansas originally what will the end results as far as damadge to secondary ignition circuit? ya lost me SORRY!!

In my experience, in an asian motor, ngks are basically the only option. ngks are by far the best plug made. Be sure to stay away from autolite, or champion for sure. I sould recommend to you an ngk v-power at .032. Keep all cap, rotor and wires oem as well and you will eliminate alot of problems.

i was looking at denso pdf file on toyota website and they reccomend plantnium pk16r11 but ya go to denso website and they reccomen pk16r8?? just do not wanta damadge truck!! cause the r11's gap is .44 and the r8's is .33, whats weird is my chiltons manual says the oem standard plug gap is .41? kinda confusing but i know it's just a flippin 93 3.0L V6 and go cheap but platnium plugs extend service life double from standard plugs and the V6 plugs are a pain in a couple places!! gotta remove air box to T/B on drivers side and back one on passengers side is tight for my big hands!! i know quite the complaining!!

Called Denso and found HELP!! purchased double Platinums and they realy pepped up the old V6! PK16R11 and set them to 32 and all is well!! except for a few battle wounds from heatshields!!

if you use anti seize, it does reduce the tourque, but not by half. when installing plugs you need to get them hand tight, and then half a turn. some plugs have differnt amountof turns required. it depends on the metal of the head, and the plug washer.

if you use a plug that isnt desinged for the engine, the ignition has to work harder to push a spark through a path that it wasnt desiged to flow. the primary circuit is the distributor sensor, ignitor and primary ignition coils. the secondary circut is the distributor cap, rotor, seconary ignition coil winds and coil wire.

well good. as long as those plugs are whats listed as OEM for that engine, it will run good like that for 80-100,000 miles.

what double platinum means is, there is a platinum pad on the tip of the electrode, and the tip of the conductor.

yep i do not have a 3/8" drive TW and my 1/2" only goes to 20 Ft Lbs which is a little over so i just did the 1/4 to 1/2 turn method described on the denso box. Guess i should start planning next project!! Clutch,PP & TBearing just wonder if i should just go OEM parts or aftermarket? Thanks for all your info!! BTW
