2015 YEC Yamaha R1 Spark Plug Set. Includes 4 - R0465B-10 NGK surface discharge plugs. New, $465/set through Graves. Works with other year R1's as well, but you should check and confirm first. $125. Thanks.
Hey, I still have a set of plugs. I'm not sure if they will work on a 2003. You may want to cross-reference OEM part numbers to confirm. Thanks.
