Spark plug question...

[gil marlin]

What is the difference between an NGK BR8HS10 and B8HS10 spark plug? I installed the BR plug by mistake and had plug fouling issues for the first time. I thought it was a load of bad gas that caused it and just found that I had used a different plug than what should be in there...

the "r" stands for resistance it is basically to keep interference if you have a radio etc connected to your system .....

Thanks, the R plugs had a slightly shorter ceramic part and I thought maybe it was a colder plug...

Make sure you set the gap, even though plugs usually come generically pre gapped you need to ensure you are operating at suggested gap

nope ... the number indicates the "hotness" of the plug ....
