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? **Q: This sparks plugs fit with the honda cr-v 2001 rd1 jhlrd18691c048156** A: Go to densoautoparts.com and enter your vehicle’s information.
