2013 Yamaha R6 Maintenance: Spark Plugs and Air Filter (How To) 

I haven't had any issues at all, everything has been working as expected, it's definitely doing it's job.

Just cycle the fuel pump before the first start after the job, turn the key with starter button on a few times and you’ll hear the pump

Yeah they are compatible. The end caps on the plugs can be unscrewed off with a pair of pliers and the coils will fit over them. If you don't take the caps off before installation they won't fit.

Spark plugs were about $10 each and I got the K&N Filter which was about $90,. I'm not sure how much a shop would charge, but I'm sure its by their labor hours. I would recommend calling around and asking for estimates if you want to go down that route.

Heyo, you have to make sure to take off the round cap ontop of the spark plugs to expose the threads then your coil packs will fit over.
