Tohatsu 50D 2 Stroke - Alternative spark plugs

[bobdyer77]

Anyone offer any advice on the difference between NGK B8HS-10 and BR8HS-10 plugs? Currently have BR8HS fitted and two spare but struggling to source a third so as to replace all three with the same. Manual says B8HS can also be used which seem a little easier to find but what if any is the difference?
Champion L-78C or RL-78C also an option but likewise seem to be a bit obscure and seems like all the above plugs are no longer stocked by many suppliers? . Anyone using alternatives to the above on your own engines

Not aware of any difficulties getting either of these plugs. Whatever Tohatsu recommend, then put them in.

Thanks for the link, I now know the difference. Found BR8HS online and in stock locally now so will pick one up to go with the other two for the next plug change but beyond that may as well replace with standard B8HS seeing as they seem to be almost a third of the price and un suppressed plugs arn't going to adversely affect me.

Can run lots of different plugs but generally BR8s will work fine. Can run 7's if you need more oil and you're fouling, projected tip for more power, extended for the billet TSR tohatsu head, iridium if your wallet is too heavy
