What kind of spark plugs are you all running ? Its getting to be about that time for a tune up so i need some help . thanks

 

NGK V-power

 

yea same here im runnin NGK V-Power whoever owned my truck before put bosch plats in there...it ran ok but when i took them out they were burnt real bad on the ends so im not sure what happened there but the v-powers seem to do a good job

 

I'm using the Bosh Plat plugs. After I installed them I read on this forum how people didn't like them. I haven't had any problems with them though.

 

ptrapper65 - I read the same thing, and I dont have a problem with my Bosch plat 2-points either.

 

Im also using the bosch and havent noticed any problems yet.

 

I use autolite 2x platinums myself, APP5224

Platinum in and of itself doesn't do anything, it just resists erosion and corrosion twice as long, thus you can double the mileage interval between changes, that's really the main reason I run platinum, it works better longer.

For regular plugs Ngk works, as does Champion RJ-12YC

 

Autolite 3923's best plugs so far..

 

Champion truck spark plugs

 

whats best for aSTOCK 4.7?
