S3 AMK Spark Plug Gap
Guys, what is the correct METRIC (mm) gap for NGK Platinum PFR6Q Spark Plugs on an S3 AMK MY01?
I've seen various figures ranging from 0.28mm to 0.32mm banded about, but as I have a metric feeler gauge my nearest options are 0.25mm, 0.30mm or 0.35mm
A quick look over at http://www.spark-plugs.co.uk/pages/technical/gaps.htm reveals that the 0.28 and 0.32 figures are Imperial Measurements (INCHES) and should be 0.028 and 0.032 respectively.
Their handy guide indicates that the 0.028 INCHES is roughly 0.70mm which my trusty METRIC feeler gauge has a blade of precisely that thickness
I did think that 0.28mm was a bit on the narrow side..
