for those who are interested in adding a bit of extra power while still keeping the stock airbox, this is a much superior alternative to runing with no airbox lid.
the fit and finish is great,
prefilter material sandwichd between two very solid pieces of aluminum.
when i initally put the lid on i noticed that it slid around a little bit and was not totally secure,
a quick trip to home depot for some foam weather stripping solved that problem quite well.
the lid fits extreemly tight right now... and after many many rides (3 months worth of riding) the air filter still looks like brand new, (cleaner than ever with a stock lid) (and i have changed the filter once compared to 4 or 5 times that i would have last season)
the power difference is noticeable, i did not tell 2 of my friends with raptors that i had bought this, last season they were out running me by a lenght or so, this year i am easily taking them by 1 or 2, that is a 2 - 3 quad length difference in about a 1/4 mile...
so for anyone that would like a cleaner air filter, and more power i would not hesitate to reccomend this...
ill get a picture of it on the machine tomorrow...
