I use free flow filters on my vehicles anyway. This valve opens every downstroke to make pistons move easier so I guess it's
working on the principle that a little very often add's up to noticably more? Seems to be a lot of plumbing just to connect it to the inlet manifold. And why a T junction? Hmm....
Perhaps someone understood it better than me? But in a 4 stroke half the strokes are power, so I pressume we are talking about the inlet strokes but what is it actually doing? That little valve that looks as though its plumed into a water hose is that the actual thing or is it controlling something in the manifold? Please explain.
Basically if I understand it right..... on one of the strokes of the 4 cycles it reduces the energy against the piston allowing it to take less energy for it to complete that stroke. This less energy means the other piston(s) are not working so hard during that cycle to do something beside turn crank. Less work to put same output thru the crankshaft is where the energy saving comes in.
