Lets just say......

Lets just say that I have a Farmall 75A that I bought new and is now out of warrenty by a little. Lets just say that she Dyno-ed at 66HP at the dealership the day I brought her home. Lets just say she handled a round baler okay but needed a little more muscle, not much, 10-15. I thought of trying something simple that may not cause major issues like turning the pump up would. Like changing the Donaldson style can air filter to a K&N cone or funnel shaped filter. Do you think I would get a HP increase? What about having the turbo "ported and polished" so to speak. Same turbo, just slicked up on the inside. What about exhaust flow improvements? No engine changes just wanted to let her "breath a little freer".

The K&N air filter should lessen the piston ring friction after the extra dirt in the cylinders makes the rings thinner the bore bigger. Not sure that would be a net gain however.

Throw that K&N crap in the bin and turn up the diesel a bit
