Bought this filter as an extra so I'll always have one ready to use... Been using K&N filters on everything I own for many years now with NO problems at all...

As far as I can tell, it does what it's meant to. I put this on before I put on my Spectre cold air intake to test it and noticed an immediate throttle difference, definitely added some power. And it hasn't messed with my mass air flow sensor. Don't buy this to save gas though, I haven't noticed much of a difference. Wasn't too hard to install either, just make sure you have a socket set and a pair of vice grips at least and you'll be fine.
