8DF verses 8DG Spark Plug Caps ?

[REARSPROCKET]

Does anyone know what the difference is between the spark plug cap 8DG-82370 for the older 97-2000 style coils and the newer 8DF-82370 spark plug caps for the newer styled coils ? besides the price, the newer ones are $5 cheaper each ? My buddie needs a new set for his 97 SX700 and we're wondering what the difference is ? Also is it better to just buy the much cheaper NGK 8020 90* resistor caps ?

Also is it better to just buy the much cheaper NGK 8020 90* resistor caps ?

It's all I have purchased.

Thanx that's a great alternative and the red ones probably look good on the Red Head.
