Make sure you clean the MAF sensor regularly. The oils in these things are pretty bad.

In terms of performance gains you won't see any. Maybe some more intake noise...

I had it in my previous car because I found one cheaper than the OEM filter, but I went and replaced it soon. I feel better if I know there is no oil flying in my engine cramming my sensors
