Just got mine
Order through cummins,$55. 00 (CDN). Seems to run about the same,haven't had it out on a long run yet. One thing it did get rid of is the little cloud of smoke when I get on it,pre-boost. Time to crank up the AFC a bit more !
I mounted it on a homemade heatshield,bent from aluminum. Bolted it to the studs,and secured the filter with 2 BIG hose clamps slipped through a slot in the aluminum. Don't know how much the heat shield helps,because I installed it all together. The engine side of the filter still gets pretty hot though,maybe the aluminum isn't the right stuff. The filter also seems to rub on the hood insulation as well,so I may have to lower it a bit.
If you are in Canada,tell Cummins to order it from the Fleetguard warehouse,in Missisauga,and they will have it the next day. They originally told me 3 weeks to get it from the US,and the price was much higher. Called the 800-22FILTER,and they told me Cummins could have it next day.
NAPA,or UAP as they are called up here,can get it as well,but the part number is different for Canada. The UAP number is 42790,and cost is $59. 00.
