More CR, more nitrous, tighter gap. Same with boost.
I have never checked the plug gap on a BR7EF as I only used them twice before I stepped up to the B8EFS plugs and I check their gap out of the box sometimes(hardly ever check plug gap and I should) and it's usually .026 but I figured(assumed) BR7's would have a looser gap out of the box than a B8EFS would.
