military distributor with civilian spark plugs-cables

[ktm25089]

hello everybody!!
i just saw at the galleries section http://willysm38a1.mypicgallery.com/
f134 right.
in the picture there is the military distributor with attached civil cables.how can i do that??
can i use the following spark plug?NGK BPR5ES

thank you

You just need to buy a civilian type spark plug lead set or several feet of good spark plug lead and use nipples that fit the distributor cap. The correct plug is a Champion J8C. (Do not use the CJ8 which is a lawn mower plug) The NGK conversion chart will get you to a good European number. There are several choices in the Champion book conversion chart.
B4, B6S, and if you want a resistor type plug the BR6S. You can try the colder B4 first and if not satisfied with it's performance move up to the hotter 6 series plugs.

thanks wes,
what's the difference with the resistor?only for the radiointerference?
because i don't have access to my jeep now.can anyone tell me how big spark cables will i need to buy them?

NGK B6S
this is the plug?so short?it's like the chainsaw plugs.NGK B6S.

found that.

As well as reducing electrical noise for radio, television and mobile telephones etc, many modern ignition systems require resistor plugs to stop electrical noise from interfering with the vehicle's on-board electronic control units (ECUs). If non-resistor plugs are used in place of resistor ones, the result can be malfunction and in some cases immobilisation of the vehicle. Resistor spark plugs should always be fitted, therefore, where specified. NGK resistor spark plugs contain a single ceramic monolythic resistor of approximately 5000 ohms. Because of the type and construction of the resistor (ie no springs), the problems of vibration and sudden changes in temperature that can occur with some other brands do not apply. The function of the resistor is to reduce electrical noise generated by the ignition system. The most effective place to situate a resistor in the high tension circuit is as close to the spark plug as possible. This makes the spark plug an ideal place to house the resistor. Because the resistance value is only approximately 5000 ohms, there is no detrimental effect on engine performance, power output, vehicle emissions etc. It is also a fact that many motor sport world champions only use NGK resistor spark plugs. In nearly all cases - apart from some very old low output ignition systems - resistor spark plugs can be used in place of the non resistor versions

i will give a try with the NGK BR6S.
the original are veryyyyy difficult to find here and expensive.
will inform with the result

thanks
