NGK plug chart! cold-hot

[The Big Al]

Thought this might be some help to some, if you need info on a differant NGK part number, let me know and I will try to get the chart.
These plugs listed seem the most common.
The last row with plug number BUZHW are resistor plugs, These are the plugs with the "R" stamped on them. Most think the "R" stands for racing. It stands for resistor.
Row 1, plug basic's
Row 2, heat range
Row 3, Old NGK part number, currently still stamped on the plug .
Row 4, new plug number
Row 5, plug style (see picture guide)
Row 7, resistor plug number
Row 8, new part number for resistor
Row 9, plug picture guide number

Thanks AL
