NGK FTW. If that's not available and I have to have something right then.......ND will usually suffice.
As for Bosch, I have removed more of those plugs from car engines for causing misfires than any other plug. I have actually removed Bosch Platinum plus 4's that were only 30 miles old cause they were causing more issues than they were stopping. I don't like 'em and will never use them again. I also only like a Champion in a lawn mower or chainsaw.
