Not long after getting my 06 I did the stock air box mod and put a amsoil filter in it since I got sick of seing my filter minder going darn close to going in the red with a brand new stock filter. well Its been about 30k and while doing maintence I knowtice it had almost pulled the minder down to red like the stock filter did. I tried to clean it out with compressed air but not muchcame out and its still pulling the filter minder down. I know they say they are good for 100k but I'm wondering how much it will flow if i keep it on there that long. 5o bucks is kinda high for a filter that only last for 30k.
