will a 2002 660 raptor spark plug coil and wire work on a 2004 grizzly 660?

Answer 1

yes, they are basically the same engine, the grizzly has a heavier crank for low end torque. That is the only difference in the 2 engines. They use the same carbs(2006 & up some are Fi) starters, cdi boxes, stators and coils.

Answer 2

there is a 100% chance that it doesnt. it is 2 entirely different models even though they are made by suzuki
