What do you guys use for a precision gap tool? I'm searching around for one but looking for any recommendations.

Thanks!

Something like this...





There are about a half dozen different brands of these on Amazon, they all look pretty much identical except for the brand stamped into the side. Should be available at most auto parts stores as well.

I have never messed with gapping the Bosch fr6ldc plugs. Always put them straight in out of the box. Zero issues on a built motor, ever. I think people try to overthink it sometimes....YMMV

Mine were pretty much exactly gapped to spec out of the box... Two were every so slightly larger, but like .035 vs. .034.

I don't think I'll bother checking them next time.
