im replacing the spark plug in my raptor this weekend, so Riva parts finder thing list the 2001 raptors spark plug as ..NGK-DPR8E-A9-00 PLUG, SPARK (NGK DPR8EA-9) (U49)

and the bike bandit lists....NGK DPR8EA-9 10PK
(UR)(NGK DPR8EA-9)

wtf, is there a difference in the two plugs?

thanks for any input

Nothing. They are the same plug.

The first number is just a Yamaha part number used to identify it.

The number by Bike Bandit is just letting you know that it must be purchased in a 10 PK [10 pack]
