300sd wastegate membrane and K&N

[GregZ]

Hi All,

Now that my turbocharger is in the smallest pieces possible, I noticed that both the wastegate membrane and the blow-off membrane are ripped (shut). Any idea where to get these (I checked fastlane with not much luck)?

Also, I read some old posts about a general discouragement for using K&N (or similar) high performance air filters and oil separators. I am not sure I am convinced. Could somone reiterate quickly for me why not use a seemingly superior product (anybody with first hand experience)?

Thanks,

Greg
