As far as the K&N ..... some have complained of turbo dusting. I personally think some were not installed correctly. Drop-ins have had the biggest issues. I pull my hose off and check turbo every oil change. I think some hose clamps get loose. Use air ratchet and not screw driver to TIGHTEN THOSE HOSE CLAMPS GOOD!!
Diesel Freak does this look like it is installed improperly. Nope sure doesn't to me. But what I do see is holes. What are those holes from sand. Where did the sand come from the sand dunes I went to for a weekend.
Now yes the filter is grey. That is because I was cleaning it when I discovered the holes. I called K&N and they asked me to email pictures to them. I informed them that I discovered the holes when cleaning the filter, I told them that it was not oiled. They said no problem they just need the pictures to verfiy that is a K&N and then they would warranty it. Now K&N did over night me a new filter. But I still replaced it with the TYmar filter. At least until I can find a new aftermarket filter intake I like.
