Out of specs daw yung ordinary na spark plug na kinabit. Ok sa simula kasi bago ( pinalitan sya last sept 2014 pa ) pero pagtagal daw magkakaproblema kasi out of specs sya.

Kaso eto nakakatawa... Yung spark plug price ni greenhills ay Php 1,280 ang isa at yung sa cainta ay Php 612 ang isa ( lumang model nang iridium ang sa cainta )
the only difference in specs would probably would be the heat range of plugs siguro... bawat model ng engine kasi ng vehicle meh specific heat range...

if the first 3 grooves ng thread is blacked, its ok, anything less than or more that (less than 2 grooves/ mroe than 3 grooves blacked) eh detrimental sa life and performance ng plugs...

ito probably and sinasabi na out of specs that eventually will lead to failure...
