Gapping Point Spark Rb20det

[MYCEF3]

Hey guys

Reeeeall stupid qusetion and i cant find it no where

What is the exact sparking mesurement for the spark plugs (RB20DET)

Iv found n bn told 1.0mm

1.1mm

0.08mm

I had them all at 1.0mm and it was missing as i was coming on boost fairly mild

took them out made them bit smaller roughly 0.9mm and its running a hell of a lot better now top end high revs is missing???

Sooo im thinking its smaller again!

Just so i dont have to take it apart again, What u guys reckon

Cheers

0.08... That would be a very tight spark (haha... tight.... )

With an N/A engine 1.1 is the standard and that is what most plugs are out of the box.

With a force inducted car you get away with what you can but most people will run around the 0.8 mark.

Also be careful with platinum plugs (which i will never use unless i own a car which is a bitch to change plugs) not to touch the electrode as the platinum coating is only a few microns thick and if you push a screw driver in their trying to gap a plug you will ruin it.
