Or buy a pair off ebay for less than $40 and you can just change them over when ever you want.
Unless your willing to actually get under and check each service you'd never know if they actually changed them or not anyway and with a 20K lifespan I wouldn't put it past some dealers to conveniently forget such a small item. Buy a pair off ebay, and get them cleaned periodically and if Nissan did whack some in there for you you'd be able to go 100K easily without worrying about buying new ones.
