Is the Donaldson AIS that I see advertised in the magazines the same AIS that sponsors like powerstrokeshop.com carry? Is there any difference?

 

I have no clue, but I have my AIS and it seems to be just fine with no problems.
sorry I am not help what so ever.

I only did it cause of scratches in my intake to the Turbo, and the finswhich are bent like some one had a stick in there while spinning. they say its a better seal from the stock one. I have a 2000 F-350 if that matters.

 

Should be the same thing. We get our AIS systems from Ford and manufacture the Foam fender sleeve to go with it.
