do splitfires help spagthorpe diesels in article c jf djr news cso uiuc edu wcd uxa cso uiuc edu daniel warren c writes earlier i was reading on the net about using splitfire plugs one guy was thinking about it and almost everybody shot him to hell well i saw one think that someone said about show me a team that used split fires well here s some additional insight and some theories about splitfire plugs and how they boost us as oppossed to cages splitfires were originally made to burn fuel more efficiently and increased power for the x cages well for these guys splitfires now i don t know about all of this and i m trying to catch up with somebody about it now but splitfires should help twins more than splitfires work mainly by providing a more or less unshrouded spark to the combustion chamber if an engine s cylinder head design can benefit from this then the splitfires will yield a slight performance increase most noticeably in lower rpm range torque splitfires didn t do diddly squat for my gmc pickup l v but do give a noticeable performance boost in my harley sportster and my best friend s sportster folks i know who ve tried them in evo motors can t tell any performance boost over plain plugs which is interesting since the xlh and big twin evo combustion chambers are pretty much the same shape just different sizes two of my friends who have shovelhead harleys swear by the splitfires but if i had a shovelhead i d dual plug it instead since they respond well enough to dual plugs to make the machine work and extra ignition system worth the expense plus they look really cool with a spark plug on each side of each head neal howard xlh dod computrac inc richardson tx doh o neal cmptrc lonestar org std disclaimer my opinions are mine not computrac s let us learn to dream gentlemen and then perhaps we shall learn the truth august kekule
