Id like to fit a panel filter to my MY02 WRX, but there seams to be question on the saftey of aftermarket filters.

If I was going to fit one, I would probably go for the K&N - it seams to be the least 'harmfull' of the lot, BUT I stumbled across THIS while looking around.

Does anyone have and more info on these, like what type are they (foam, cotton) and any prices. I would just like to know your thoughts before I mail SM.

Thanks

 

Green Cotton Filter perfectly safe.......
