Diff between 20k & 40k B Service...

Looks like the only difference is the 40k service replaces the air filter.
Can anyone see any other that I may have missed?
So I would assume that the dealer will charge roughly the same for the 2 B services?
Also, saw that my local dealer has a coupon sale $399 for B service, & $179 for A service?
Good deal?
Thanks,
