I had the intake of today and i looked at my turbo it is black around the inside of it.is that normal?

 

Dust accumulates and is dark. You might need a better filter or there could be air air leak, bypassing unfiltered air. Craig

 

Its got an k&n air intake on it when I run my finger threw it it was like grease.I didn't know if it was maybe a sealor something going out I don't want to experience a run way engine lol.thanks for the response Craig

 

Most folks will tell you ditch the K&N. I've seen 'em do bad things to these trucks.....especially if you over-oil the filter. The turbo will actually suck the oil through the media and in the end you have what you are seeing.....dirty turbine blades. There are some really good dry filters on the market nowadays. I run one of Amsoils dry filters and after 2yrs of use (and only 3 cleanings ) the intake plenum and compressor wheel are spotless!!

 

Okay thanks guys Ive heard people say when they c that thats oil leaking from the seals in the turbo.but I didn't think about it being oil from the filter.I've been wanting to go to a better air intake anyway so guess that my next upgrade any suggestions ??

 

S & B makes a good filter, Amsoil is what I have. Those two are what's coming to my mind right now but there are others out there.

 

I know a lot of people are anti-banks, but their CAI has a 7" opening. The only other intakes Ive seen that are as big in the back as the filter is have been home made.
