Difference in B7HS -10 and BR7HS-10 Spark plugs

[99yam40]

My C40TLRX calls for B7HS, even has a sticker on the motor.
and I clicked on those on the parts web page for my motor when I ordered them, but I got the BR7HS.
will this be a problem to use them or do I need to get the B7HS?

I am sure the R stands for resister ,
Would the resister cause a higher spark voltage?
From what I remember on automotive Nonsolid wires and resister plugs helped reduce noise in radios.
looking to see what all this parts web site shows for the BR&HS plug it is higher HP motors 150hp and 200s

This place is getting ridiculous. Onerous. Keeps blocking links to useful websites.

NGK says a non resistor plug provides more energy. Appears that you got the wrong plugs.

Although in reality it might not even be noticeable.

I guess I will try them and see how it goes

Amazon has them. The resistor plugs will work.

clicking the Yamaha Parts at top of page shows them for $4.20,
but you may get the BR7 instead. Like I did

Forget that..they want $20 to ship. Looks like Napa online has them $4.29 USD plus shipping, dont know how much that will be.

I was ordering a new set of seals and housing for my drive shaft anyway, and also a set of plugs for my brothers C60 (B8) along with the B7s for my C40.
shipping was $9.95 and then taxes.

Will try napa next time is I am not ordering other Yamaha parts
