Stage 1 SE for Street 750, Spark plug upgrade?

When I asked for a quote from my dealership for Stage 1 Screamin' Eagle, they added a few parts that I wasn't expecting:
1) An upgrade to the spark plugs
2) Spark plug wires

But I've seen people go for V&H Slip-On Exhausts and K&N Air filters/ V&H O2 filters without changing the sparkplugs.

Any reason behind this? Should you upgrade the spark plugs even when using these aftermarket parts?

PS:
The part names mentioned in the quote are:
1) SE ST PERFORM SPARK PLUGS
2) SE 10MM PHAT SPARK PLUG W

I think you dealer just saw an opportunity to sell a couple more parts. Unless there is a problem that you haven't mentioned, just tell him to not bother with the plugs and wired.

As above - no reason whatsoever why these items would be changed. The HD site is quite specific about what they do:
