David, there are many guys who have blown their turbos because of this filter. Most (including me) do the frequent oil changes too. Problem is, the filter is too small. Just do it , then your turbo will last a very long time. My box went for 18 months at around 380 - 400 rwkw before it started to complain. It lasted another 6 months before the rebuild became a necessity.
