Anybody know if it's hard to install a sunroof deflector or should i have it professionally installed by Nissan. Any tips would be greatly appreciated!!!

 

It's ridiculously easy, all you need is vise girp (or the proper wrench) and a screw driver. It's nothing to be intimidated by, 2 bolts, that's it.

 

I take mine off every winter, some take them off every time they wash their cars. Takes 10 minutes if you take your time. Sometimes you can get a little backsass from the clips, if so it will take you 11 minutes. There was another thread on this a few weeks ago.
