Hi. Im wondering what glow plug to use in my evolution 61nx. i know that evloution says to use their "super plug", but i heard that an os a3, or old #6 works. now, since my lhs didnt have the evo plug, (and they NEVER have what im looking for) i went with the a3. the a3 is a shorter plug, which means less compression, but its a hotter plug, and supposedly will ignite the fuel more completely. my question is, is there a plug out there that is as long as the evo plug, but hotter? in my mind, that would be the perfect plug. the engine runs well, but does let fuel slip by. im going to try the a3 as my evo plug took a crap on me yesterday. all you evo guys, let me know how my idea sounds and also if there is such a plug. thanks. everyone else, if you know of such a plug, chime in too!!! lol, thanks for any input you guys have.
