250-500cc BR8EG or B8EG

I'm still freshening up my new to me 09 WR 250.

I went to the local shop and asked for an NGK B8EG. I didn't notice that the guy gave me a BR8EG.

Bike currently has a B8EG. Shop manual says BR8EG should be used.

Is it ok to go with the manual (R-plug) after the PO had it running well with the non-R plug, which isn't stated in the manual?

I searched here and NGK site and think it is.

Manual's recommendation should be fine.

Resistor vs. non-resistor shouldn't matter much in this application: http://www.ngksparkplugs.com/techinfo/spark_plugs/faq/faqresistor.asp

Thanks didn't see that on their site.

Go for non resistor b8eg as most plug caps are suppressed 5k ohms, have had them break down and cause non running issues, new plug sorts it for a hour or so then boom stops again.
Unsurpressed plug and cap after all it doesn't interfere with your tv your on the bike so who cares.

WR does not require an R plug.

At least the 04 model does not.
