Message: [QUOTE="lincolnlocker, post: 1170137, member: 944"] this is for the guys who drive in the worst conditions and still want some gains over the stock airbox.. i have tried every cone filter, wet or dry, on my dually 7.3 and they all at some point dusted my intake.. to this day i refuse to run a cone filter... i would really love the no limit intake from bigr but i just cant do it.. so this is what i decided to go with as i have one in my 01 7.3. so i figured i would try it here.. its a big ***in filter. its 10.5"x10.5" so its tight.. it still wiggles so its not super tight but it wont move much.. this is the filter number by donaldson[IMG]http://tapatalk.imageshack.com/v2/15/02/17/59392544e51503ba89b9068b60e63287.jpg[/IMG] reference from stock filter to this one[IMG]http://tapatalk.imageshack.com/v2/15/02/17/4f7dfc235860ca874f29f8b890d3a14e.jpg[/IMG] i just used a stock lid and cut it off exactly the width of the clamp i was using, a 4" to 4" boot that you can see is stretched some but it fit good, a 5" long piece of 4" exhaust pipe, and three stainless t bolt clamps.
