**Q: are these gapped at 0.4 and are these able to be gapped to a different size?**
A: i belive i double checked and they are all pre gapped very accurately.  i dont remember if its gapped at 0.4 but i know for sure you can re gap them to whatever spec you want.  I think on my bmw the pre gap is narrower but i installed them anyways due to the gap might widen as you hit more miles?  so it will still be within spec.  I was told a little narrower gap creates better jump of current so i might have an increase of 1 or 2 hp?
