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.
