Hi all

I was wondering if somebody could tell me the correct gap for a set of Iridium NGK spark plugs that I have just bought for my 56 plate Cooper park lane.
The manufacturer says leave them as they came as the centre electrode is very delicate, the thing is I have a proper spark plug gaping tool and have been gapping plugs for 30+ years.
The reason I want to know is they came set at a different gap to the mini supplied plugs, and each of the new ones is fractionally different when I got them out of the packet, I would just like a reference to set them all to.
Thanks any help much appreciated.

Hi

Here is a good link everything you will need :-)

I have set mine to 0.032" seem to be better for me on my MCS

Run them for a few hundred miles and retourque them the plugs on these mini's seem to loose the TQ

Hope this helps
