what model should be used? would just regular ls ngk work? i heard different story about modified spark plugs work better what are everyone view and experience thank you.

 

i use regular ngk..there is a tiny sticker on my jdm engine that suggest use some certain model of ngk spark plugs.

 

I used NGK V-power BKR6E-11 (stock gap)

 

could some break it down on using spark plugs for certain compression ratio.

for example . lsvtec 11.0 c/r which plugs hot or cold?
i just want to learn more about picking the right plugs for certain setup thanks.

 

the higher the compression the colder plug you want

11:1+ you want to run an ngk 7 or 8 heat range plug
