071 spark plug question

[Fordmad2012]

Just had these ford Plugs come 4 my Ecos and wondered if you can put them straight in? Or do I need to adjust the gap guys?

0.6mm to start with on standard ignition. You can use a slightly wider gap on a group a coil and even wider on wasted spark. I use 0.65mm on a group A coil and decent newish leads and havent had any problems.

I got told it was .55 for group A?

The come pre-gapped to 25 thou. Basically you want to run the biggest gap you possible can without them misfiring....

I think I set mine to .6
