I inventory -5 through -9 NGKs and run -9s (coldest) in my GT which has a modest build, maybe 11.5:1 CR and Richard Good GP3 cam. Factory heat range is - 5 or -6 per NGK depending on if it's a GT or TR.</span></div><div></div><div id="yui_3_16_0_1_1429817306959_8136"> </div><div class="signature" id="yui_3_16_0_1_1429817306959_8137">Brian Schirano<br>585-305-0349 Cell <br>BSchirano@yahoo.com</div><br> <div style="font-family: verdana, helvetica, sans-serif; font-size: 16px;" id="yui_3_16_0_1_1429817306959_8177"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;" id="yui_3_16_0_1_1429817306959_8176"> <div dir="ltr" id="yui_3_16_0_1_1429817306959_8175"> <hr size="1" id="yui_3_16_0_1_1429817306959_8212"> <font size="2" face="Arial" id="yui_3_16_0_1_1429817306959_8195"> <b><span style="font-weight:bold;">From:</span></b> Robert M.

I have a collection of different temp range plugs from Accel <br>all the way from 113 through 117. I've never taken the time to play on the <br>dyno to see if there's any difference changing heat range. I know = "my <br>bad". I've never had a plug fail despite the amount of internet detritus <br>regarding the quality of this brand.<br><br>In any case I was thinking about switching to NGK. My TR6 motor is 12:1, <br>Webers, cam (street duration Isky Z19), header, etc. Ignition is Mallory / <br>Pertronix.<br><br>Would the NGK BP6ES or BP7ES be a better choice?<br><br>Regards,<br>rml<br>---------------------------------------------------------------------------<br>Bob Lang Triumph TR6!! | This space for rent<br>Former NER Solo Chair |<br>Voice:617-253-7438 | Cell: 339-927-4489<br>---------------------------------------------------------------------------<br>_______________________________________________<br><a ymailto="mailto:fot@autox.team.net" href="mailto:fot@autox.team.net">fot@autox.team.net</a><br><br><a href="http://www.fot-racing.com/" target="_blank">http://www.fot-racing.com</a><br><br>Donate: <a href="http://www.team.net/donate.html" target="_blank">http://www.team.net/donate.html</a><br>Archive: <a href="http://www.team.net/archive" target="_blank">http://www.team.net/archive</a><br>Forums: <a href="http://www.team.net/forums" target="_blank">http://www.team.net/forums</a><br>Unsubscribe/Manage: <a href="http://autox.team.net/mailman/options/fot/bschirano@yahoo.com" target="_blank">http://autox.team.net/mailman/options/fot/bschirano@yahoo.com</a><br><br><br><br><br></div> </div> </div> </div></body></html>
