Well since the new search blows I'm just gonna make a new thread..

What's the right gap for spark plugs for a b16a2?

I just bought some NGK iridiums and the stock gap was like .30-.35?

Is that okay or do they need to be gapped?

Thanks

you have to be very nice to iridium plugs, or you will break the tip.
what mods are dont to the engine? does it misfire with the gap that loose? if not, let her eat.

 

Yeah I've heard that the tips on these break very easily.

It's a stock b16 (90k miles) with all bolt ons (I/H/E) and a CTR intake cam.. The timing is a bit advanced as well..

It doesn't misfire, and seems to run good as is. What do you think?

 

bump need to know.

 

According to the Helms manual you should not adjust the gap on platinums. I don't know if that applies to iridiums as well.

Anyway the gap they specify for regular ones is .052

 

1.0-1.1mm

.040"-044"
