I use NGK V-powers on my L28E with a Turbo slapped on it, shooting at 10PSI gapped to .032 and I love it everyday. Not sure why I gapped it so low, but it does feel a bit nicer in boost now that I did. Stock gap is .044 but I remember some of the plugs not being gapped there, so I was thinking about regapping my plugs to .045 or so. She ran fine either way but seems smoother with a smaller gap
