8 is hotter than 9 (toolmanx3)
The NGK DP7EA9 and DPR8EA9 are both spark plugs, but they differ primarily in their heat range and design. The DP7EA9 is a direct replacement for certain applications, typically featuring a slightly hotter heat range, while the DPR8EA9 has a cooler heat range, making it suitable for different engine conditions. This difference affects how each plug performs under varying temperatures and engine loads, influencing ignition efficiency and engine performance. Always refer to your vehicle's specifications to choose the correct spark plug.

Cj8 is hotter than cj7
A spark is a visible electrical discharge caused by a sudden release of energy. Lightning is a large-scale spark that occurs in the atmosphere during storms, typically between clouds or between a cloud and the ground. Essentially, a spark is a smaller version of the phenomenon of lightning.
the time it duration for the action and voltage drop
Basically they are for different climate/riding conditions.
the R stands for Resistor. It is a resistor plug.
