Wanted to get some thoughts. I have a Superior XP-IO-360-B1AD2 and some folks have recommended the UREM37BY plugs over the 40E plugs I have been running (for the slick mag - running IK27 with the light speed).
On the Tempest chart, they do not show any plugs acceptable for Superior engines except the 40E.
Can I and should I run the UREM37BY in this engine or not a wise idea? I hear they foul less but is there any other benefit over the 40E or just stick with the 40E?
Thanks!
