  • how can i know if my spark plug have a resistor or not?

  • what is the temp rating of that type of plug?

  • I tried a Bosch Platium and had the same luck as you did, broke shaft. The champion plugs have worked out the best for me.

  • I hacked and chiped away the plugs in order to find how long the core piece is. That is the piece one is aiming to remove through heating and unscrewing, in order to remove the resistor.

    After watching your video again, i noticed

    your core piece was multiple times shorter than in the 2 plugs tried so far. So it looks like the longer the core piece is, the weaker it is, and more chance of breaking.

    When i can, i hope to get some used plugs from a mechanic.

    I will share my findings here.

  • Try to find a Champion Plug like this or a plug out of a lawnmower, motorbike, something like that. Every one I tried with these numbers will screw off. Bosh, NGK plugs have a long post and will break. Broke sever of those plugs before I found these sport plugs from Champion.

  • @mdbreedi

    I am still having trouble getting the resistor out. I was able to get the spring out. do you have any direction for me. I am using a champion spark plug.

  • Hey, thanks for taking the time to create the video and share with us.

    I did try this with two plugs;

    1=Denso Japan. Made for an Australian car. I heated it about the same time like in video, but the shaft snapped.

    2= NGK, a Japanese brand. Heated it for a much longer time, but that also broke the shaft in the plug. After chipping ceramic, i found thread and resistor around where the outside plug thread is, so am thinking it needs even more time for heat to reach it.

    Any ideas anyone???

  • how much voltage do you think you need.

  • WIth my setup it starts to plasma around 180VDC.

  • As far as the high voltage or initial sparking goes, it is well known that a larger gap requires a higher voltage, which leads me to think that the plasma voltage required (after the spark ignites of course)may differ according to plug gap, & possibly to a lesser degree governed by some other factors; eg compression ; type of liquid (Petrol/ gasoline, water, or whatever); Just something to keep in mind with experimentation for your own setup.

  • Do you think its good for a car removing the resistance to get better spark in the engine? I heard they are there to not generate noise with the radio but i dont care about the radio! :) ?

    Thanks

  • It depends on what one is wanting to do. Removing the resistor is preferred for the experimenters trying to duplicate the high current for what i think might be a plasma in the engine of a fellow who ran his car on water. S1r9a9m9 is his yahoo forum name. I do not think his recent coil design replication attempts are sufficient to replicate the characteristics of the coils in the relays he uses in his car at the moment. Although it may demonstrate the principles.

  • I believe the resistor is there for the temperature rating of the spark. ALL the sparkplugs are the same, expect for two thigns: the thread legth or type and the temperature. The number on it say BR9ES

    B is the type of sparkplug

    R means it has a resistor

    9 is the temperature, thats the lowest so 0 is no resistance 9 is high

    E is extended thread

    S is Silly ( i dont know)

  • cant wait to see all of your plazma stuff!!!

  • Thank you!

  • Im having trouble finding that specific spark plug 8339, so i bought a champion marine plug and its got 0 resistance w/out having to remove anything.... Will this have the desired effect?

  • Give it a try, the plugs with a resistor was giving me a problem till I just took one apart and replaced it with the wire. I think it will work if your getting no resistance thru the plug.

  • thanks Redd, that helps out a bunch

  • Thanks for giving us the Nut's and Bolt's info. Your vid's are very informative.

  • excellent and made to look simple for all us simple folk.please look at you tuber fredrik999z his plasma ignition may well go welll with this if you can get heads/internet together cheers great vid once more.

  • i can see the restistor burning inside the ceraic when i run mine =]

    i must try one one without.

    thanx for that

  • thanks for the tip ... I needed that ...

  • AWESOME!!!!!!

  • You're very kind..Thank you very much...

  • cool this is going to help a lot of people dreamyear to be specific hes just been busting them to try and figure it out "Keep up the great work FOLLOW THE HYDROGEN DREAM"
