Damnit Bob Posted October 2, 2011 Report Share Posted October 2, 2011 does anyone get there plugs? I usually just throw plugs in from the box, but I know some people gap their plugs. what is the benefit? what gap should I use? I run race gas in my 4mil dunner.

n2otoofast4u Posted October 2, 2011 Report Share Posted October 2, 2011 whatever they are outta the box it the way of the fast!! Quote Link to comment Share on other sites More sharing options...
Damnit Bob Posted October 2, 2011 Author Report Share Posted October 2, 2011 Yeah that's way I expect most people use em Quote Link to comment Share on other sites More sharing options...
Dicklez Posted October 2, 2011 Report Share Posted October 2, 2011 The manual says .028-.031. I go .030. Quote Link to comment Share on other sites More sharing options...

locogato11283 Posted October 2, 2011 Report Share Posted October 2, 2011 I run them straight out of the box. Quote Link to comment Share on other sites More sharing options...
UberBricky Posted October 3, 2011 Report Share Posted October 3, 2011 I always check the gap on plugs, I'm running .30 also. IMO, the benefit is knowing you are consistent wit your setup. Quote Link to comment Share on other sites More sharing options...
dirtydownunder Posted October 3, 2011 Report Share Posted October 3, 2011 under extreme conditions the gap can be too large, and the spark can actually blow out (like a candle) you close the gap up, so the spark has less gap to jump and doesnt blow out. i dont know how extreme and banshee motor has to be, but some builders recommend a .024" gap. i ran them as they are out of the box.

06specialedition Posted October 3, 2011 Report Share Posted October 3, 2011 Mine go from the box in the bike, no issues. Quote Link to comment Share on other sites More sharing options...
guns4children Posted October 5, 2011 Report Share Posted October 5, 2011 I'm glad everyone is saying from the box to the bike. I don't have the tools to know what .030 is nor do I know how to gap a plug. Quote Link to comment Share on other sites More sharing options...
UberBricky Posted October 6, 2011 Report Share Posted October 6, 2011 A plug gapping tool can be had for less than $5. Obviously, they work well out of the box. I'm used to gapping the plugs in my supercharged mustang so the spark doesnt blow out, for the 23 seconds it takes, I'm good with doing it. I'm just anal like that, the way I look at it is do you think top fuel dragsters run plugs out of the box? Not the exact context, just my frame of mind. What can I say, I can tell the old lady I need to gap my plugs, grab some beer and she'll leave me alone for a couple hours! Quote Link to comment Share on other sites More sharing options...
UberBricky Posted October 6, 2011 Report Share Posted October 6, 2011 From NGK's site, I got curious to see what they recommend: 3. Gapping Since the gap size has a direct affect on the spark plug's tip temperature and on the voltage necessary to ionize (light) the air/fuel mixture, careful attention is required. While it is a popular misconception that plugs are pre-gapped from the factory, the fact remains that the gap must be adjusted for the vehicle that the spark plug is intended for. Those with modified engines must remember that a modified engine with higher compression or forced induction will typically require a smaller gap settings (to ensure ignitability in these denser air/fuel mixtures). As a rule, the more power you are making, the smaller the gap you will need. A spark plug's voltage requirement is directly proportionate to the gap size. The larger the gap, the more voltage is needed to bridge the gap. Most experienced tuners know that opening gaps up to present a larger spark to the air/fuel mixture maximizes burn efficiency. It is for this reason that most racers add high power ignition systems. The added power allows them to open the gap yet still provide a strong spark. With this mind, many think the larger the gap the better. In fact, some aftermarket ignition systems boast that their systems can tolerate gaps that are extreme. Be wary of such claims. In most cases, the largest gap you can run may still be smaller than you think. Quote Link to comment Share on other sites More sharing options...
