+1 on the OEM refills. Work great and take 2 minutes to pull and replace. I seem to go through them a bit faster than I expected - every 6 months or so. My dealer was charging upwards of $20 for a set, a huge ripoff. I found them way cheaper on nissanpartszone.com - ordered 4 of each (passenger and driver) for a little over $50 shipped. Part #s: 28895-CB08C (driver side) and 28895-JK61A (passenger side).

 

/\ Awesome info. I'll look those up. Thanks!
