Always used NGK in my Volvo's and never once had an issue, I just buy them from euro car parts for about £10 for four, I know I'm getting the real thing then.

Gap should be 0.7mm, they probably won't be 0.7mm from the box so don't just stick them in without measuring first.

I use Bosch super 4s in every car I have owned, never had any issues.
NGKs in any motorbike.
