ok i'm turboing my car this weeked and i was going to go buy the plugs

my question is what is the part # for the ngk plugs for a turbo sohc (d16y

 

ZFR6F-11 One step colder

ZFR7F-11 Two steps colder


I had a Y8 and I used the stock plugs which are the ZFR5F-11 with stock gap and I ran fine but do what you want.

 

thanks

 

.028" gap owns you.

 

i thought it was .030

 

do you realize how minute the difference of 2 thousandths of an inch is?

 

R5671A-8 or 9,

short reach, less likely the ground strap will melt.

 

whats this grounding strap you speak of?

 

What is stock gap set at?

stock gap is 1.0-1.1mm, .040"-.044"

the ground strap it the little piece of metal that goes from the side of the plug towards the tip, where you check the gap at.

Extended nose plugs, like factory plugs, have a longer ground strap, takes heat longer to disapate, there forethey melt easier.
