richybanshee Posted November 19, 2007 Report Share Posted November 19, 2007 I was surffing the net looking for interesting things and I found something about spark plugs. It seems Denso, Champion and NGK have been manufacturing the Iridium spark plug. This is the site: http://www.sparkplugs.com/results_appOther...2898&mfid=1 The spark plugs are for the Yamaha Banshee (BR8EIX). The center electrode is thinner 0.4mm for Denso, and 0.7mm for NGK and Champion. From the info in the site, the Iridium has a 1,200 F higher melting point than the standard Platinum spark plug (BR8ES). "Originally designed to improve starting and reduce fouling in two-stroke engines, this design was found to improve performance in four-stroke engines as well. All operate on primarily the same principle, a spark plug with fine wire electrodes will perform better than a traditional plug. There are two reasons for this, first is because a smaller center electrode requires less voltage to jump the gap. This means fewer misfires, which should be seen in higher mileage and more horsepower. The second reason is smaller center electrodes reduce quenching." (from the site) I will like to know if someone have use this sparkplugs and/or recommend using them? :cool: Quote Link to comment Share on other sites More sharing options...
Bansh-eman Posted November 19, 2007 Report Share Posted November 19, 2007 you wont notice anything power wise by switching to them. they claim to last longer. the only problem is a fouled plug is a fouled plug Iridium or not. just stick with the NGK BRE8S (assuming your running resistor plugs) Quote Link to comment Share on other sites More sharing options...

Made it much easier to start the quadzilla. I have no starting issues with my shee so I run the standard BR8ES. I think I read one here somewhere that the banshee engine does not like any plugs but the BR8ES but I could be making that up. Quote Link to comment Share on other sites More sharing options...

shanYE west Posted November 19, 2007 Report Share Posted November 19, 2007 I used to run them in my dune motor.. didn't notice any power gains or easier starting.. Just a thinner wallet after I left the store. Quote Link to comment Share on other sites More sharing options...

Would I benefit from a non-resister plug? Quote Link to comment Share on other sites More sharing options...

Would I benefit from a non-resister plug? no you wont feel any differance. it only to shield the plug from ingition interferrance. and vice versa Quote Link to comment Share on other sites More sharing options...

blowit Posted November 20, 2007 Report Share Posted November 20, 2007 I dont have a dynatek but I still run the BR8ES. Would I benefit from a non-resister plug? The resistor type plugs are used to help collapse back voltage from when the plug fires. There is a return voltage that can harm sensitive electronics and create noise in audio systems. Bests to use the resistor type plug but the non-resistors have been used for years without issues. Brandon Quote Link to comment Share on other sites More sharing options...
shee4speed Posted November 20, 2007 Report Share Posted November 20, 2007 I used to run them in my dune motor.. didn't notice any power gains or easier starting.. Just a thinner wallet after I left the store. Thats funny stuff right there. B8ES for me. No troubles. Quote Link to comment Share on other sites More sharing options...
JET 99 Posted November 20, 2007 Report Share Posted November 20, 2007 if you run a nology coil and wire setup they recommend using non resistor plugs b8es all the way for me..... :thumbsup: Quote Link to comment Share on other sites More sharing options...

Dave I. Posted November 20, 2007 Report Share Posted November 20, 2007 I have heard of people using the iridium plugs in cars and saying they suck. I guess the little iridium tip burns off or falls off and who knows where it goes. Ill keep running the br8es. Quote Link to comment Share on other sites More sharing options...
FireHead Posted December 2, 2007 Report Share Posted December 2, 2007 you wont notice anything power wise by switching to them. they claim to last longer. the only problem is a fouled plug is a fouled plug Iridium or not. just stick with the NGK BRE8S (assuming your running resistor plugs) The only difference that I noticed switching to them is that they seemed to last alot longer. I had a set last me an entire season. However, I am back to the BR series of plugs due to the fact I am fooling around with jetting again. :geek: Quote Link to comment Share on other sites More sharing options...
Swaie Posted December 7, 2007 Report Share Posted December 7, 2007 I run the br7es that is a little hotter plug. Is that bad. Quote Link to comment Share on other sites More sharing options...
