Gap for NGK Iridium IX BPR6EIX Spark Plug (BPR6E-IX 6637)

[A500TVR]

Hi,

I am about to fit a set of NGK Iridium IX BPR6EIX Spark Plug (BPR6E-IX 6637) to my 500 and I was just wondering what I should set the gap to?

I know that there is lost of debate about this new technology or stick with the original but I guess it is 2013 and maybe things have moved on!?

To be honest it is a good excuse to get the bonnet open on the Griff and have a play...

Regards

Steve
