I am wondering how many other members have converted to the pleated paper type filters? Earlier, had I known that the filter ring was reusable, I would have cleaned it back up and reused it. But then a thought came to me that the paper type filter can catch more trash than the ring type. This is probably why the conversion was made....I'm just guessing. Anyway, so far the power steering is working like it should with no binding or leakage except the front seal which has slowly leaked since I bought the car and I know I will have to replace that front seal some day.
