I just bought mine a 2 weeks ago directly from Mag-Hytec. The price was just about the same as anywhere else I have looked. All said and done I ended up paying $302. 00. I agree with Mark Craig on the aspect of it not lowering the temps all that much, but the reason I bought it was to simply put more fluid through the transmission. I think of it as by the solution to pollution is dillution (more fluid less pollution).
