Hi, Al....I have been using NGK BR9EQ plugs. Then I tried some NGK B9EGV plugs, and I could not screw them all the way into my engine with my Craftsman deep socket, because the length of the plug left sticking out of the engine was still recessed partway into the spark plug hole, and the socket kept slipping off the hex portion of the plug, which would not allow me to tighten the plugs. Both plugs are identical in length below the sealing washer....it's just that the height sticking out of the engine is shorter on the B9EGV plugs than it is on the BR9EQ plugs. I went to AutoZone, and they substituted an Autolite 2526 plug for the BR9EQ, and it measures the same as the BR9EQ plug, and I could install it with a standard deep socket. Unfortunately, I don't know what the R or the EQ stands for....just know they are much easier to install. Perhaps someone can shed a little more light on this subject. Thanks.

Okay Paul,

here we go:

NGK BR9EQ, means B = dia.14mm,=20 R Resistor Type (I think that cuts on radio=20 interference...), 9 Heatrange 9 (2-11, hot to = cold),=20 E Threadreach 19mm, Q 4-ground=20 electrode

NGK B9EGV, means B = dia.14mm,=20 9 Heatrange 9, E Threadreach 19mm,=20 GV Gold-palladium centre electrode, Special = construction=20 of V-type

Check the rest of NGK at http://www.spark-plugs.co.uk/pages/technical/ngk_symbol_code.htm
