Where to find 4.0 Disco 2, dual fire spark plugs NGK BKR5EKPB

I just returned from my local Landy dealer who could not supply me with replacement plugs (dual fire) for my Disco. Instead they carry single fire Champion @ $16.00 canadian! Ouch!!!

There was some debate at the parts counter regarding the need for dual fire. One partsman claimed a very obvious difference in acceleration while another said there was nothing significant at all. Any opinions as to should I, should I not replace with same NGK BKR5EKPB, and where might I find them at a reasonable real world price?. TIA

I doubt there's a lot to be gained, provided the ignition is working properly. You can get ones with 3 or even 4 electrodes, and I give you good odds that they mostly only make 1 spark... About the only thing I can think would make a difference is that micro-scale differences in the mixture might mean that one or another spark-path is more viable, which could have a fractional (and minimal) difference to the spark timing.

I have wondered about the function of "splitfire" or multi electrode plugs. the HT is going to find the least resistive path through the air/fuel mix and discharge through that - IMO it will not create a second or third spark and intensity will be down to the HTV applied. better spending the cash on leads, coil and dizzy IMO.

I did try 'em on something, made no discernible difference.
