ASK THE MXPERTSWHAT PLUG CAN I RUN IN MY HONDA CR250 & WHAT DO THE NUMBERS MEAN?
Dear MXA,
The spark plug that I am supposed to use in my CR250 is an NGK BR9EG-N-8. I went to my local dealer and he didn't have one so I bought a BR9EG instead. Can I use this plug without any problems?
The quick answer is that you can run a BR9EG instead of the BR9EG-N-8. In BR9EG-N-8 the alphanumerics can be translated thus:
The B means that it is 14mm thread size.
The R means it is a resistor type.
The 9 is the heat range (9 is colder than 8).
The E is the thread reach. E represents 19mm.
The G means it is a fine wire nickel alloy electrode.
The N means it has a side electrode.
The 8 (at the end) means it is a wide gap plug (0.8mm).
The BR9EG that you want to use is fine...depending on weather and gas you could also use a BR8EG (a little hotter plug).
If you have a question, send it to mxa@hi-torque.com
