That one doesn't surprise me. Fram was 'perhaps' the only filter manufacturer left that made a distinction between the two applications. Others have long combined the two applications into one. Slight size difference and insignificant bypass difference (3593a bypass psi within the 9688 bypass psi range). So really, Fram just joining many other filter makers now.
However, IF they are doing away with the longer 4386 and selling the shorty 4967 only, I would be surprised. But, with First Brands calling the shots I suppose anything possible. Time will tell.
