That should definitely be something you can do yourself with little to no issues. That's one of the first mods a lot of people do and there are a lot of posts on here about how easy some people, that have never done anything to a car, say it is.
Make sure you attach that filter nice and snug. I noticed on my K&N that the filter was working its way off and I am glad I checked it. It was either loose to begin with or the heat and vibration caused it to start slipping off. I am talking about the large ring that holds the air-filter to the tube flange. :thumbsup:
