I wasn't sold on the K&N setup so I just bought this to use instead... I called and spoke with them and they seemed very nice.

Our quads use the same stock filter (77306015000) as the 2007 450SX-F, hopefully I will have it by this weekend!

Hello,

We are using the Twin air powerflow kit for some time now and I think it's a big improvement over the stock filter, especially the cage on which the filter is mounted.

Cool! Thanks. Is that a dealer item? or would I have to order direct?
And did you get an extra filter to swap out when the other is getting washed and dried? Or do you think they dry fairly quick?
Thanks for your help.
i didnt order an extra filter because it uses the same filter as stock.

i got this yesterday and installed it last night. i am very impressed with the oem fitment of the twinair powerflow kit. no modifications were required, it took about 3 minutes to install.

i will post pics of it monday evening when i take my build pics...

So is it worth $140? Does the stock screen hinder flow that much? I was going to cut mine tomorrow but if there's another benefit to using the Powerflow one. . . . .

i think it is well worth it, i mean the powerflow has a small billet frame compared to the bulky stock plastic piece.

i will try and get some pics of it tonight!

So the backfire proof filter does not need to be used with the powerflow frame?

twinair claims that the powerflow requires the backfire filter but i have found that you dont have to use it. i have used both the stock filter as well as the backfire filter with the powerflow billet frame...
