what people dont know is what is the difference between copper plugs platinums plugs n iridium plugs,
4 tipw ill surely be better than single tip,
does any one know the reason?
its cuz 4 tips prevent the spark from spreading
economy wud be better,slightly yeah,not much though,
my experience on my car,n 10+ more cars on my friends wasnt good with 4tip plugs,when u use iridums or platinums n compare em with copper plugs,u will surely feel way lota difference
+ one can always check out the internet reviews on the 4tips n people will know wt there using,prb is they dnt know how they actually work,y the tips r 4 n wts the difference between 4 tip copper n single tip iridiums or platinums
