Dual Tipped Sprakplugs?

What is the point to the dual tipped spark plugs now that platinums and iridiums are available? I'm sure that even with the waste spark system on the 5VZE one would get as good or better life out of iridiums or platinums compared to stock dual tips.

 

if you open your hood and look at the timing chain cover, toyota actually reccommends these plugs for the 3.4...I'm not sure why thou. I run single ground ngk's in my 96 3.4 and i havent noticed any problems.

I'd assume it has something to do with better fuel burning with the dual electrodes

 

rip off... same as with the quad and octo tipped spark plugs
electricity will ALWAYS take the shortest (least resistance) path
it will find the closest tip and then it will only use that tip
as long as you use a good quality spark plug iridium, platinum, ngk, champion, w/e you'll be good to go. i'd just put the oem plugs back in if i were you. i have about 100000+ km before i'll even worry about them

 

Your signature cat file is pretty neat.... where did you get it?

 

wow not even a thank you
