Posted September 7, 201213 yr I have one ufo mag sytle btl right now that I am using, has the cooling and the high-xmax coil....I have had it since new and remember there being an option for the heat ring(pretty sure thats what it was called,) I got everything but that option...would a btl with the heat ring be ok to throw in with mine that does not have that?Thanks
October 17, 201212 yr Author What exactly did that option do, but its 100% ok to run one with and one without?
October 17, 201212 yr Just lowered inductance and made the cooling work better due to a better compression ratio. Yes it will work fine.
