I really don't understand why people don't put proper filters on their turbos, yet when they run N/A they do?

Boost or not, the motor is sucking in a bunch of CRAP

 

Wow, I can imagine it would.
What do u use on the intake side?

 

unfortunately nothing right now not by choice though, my turbo has a 4" inlet and i can't find a filter big enough to fit it. it's a brand new turbo and only has about 1k miles on it, so i don't think it's done any harm *yet*, but i'm ripping my ps and cc out so i can get a 4"-3" reducer on there and have room to make a nice little intake. i prefer not to run anything, but i don't want to ruin or shorten the life of my brand new little monster :P

 

I had a problem with finding a specific filter size on my older car which had a diy intake and someone showed me a page from K&N's site where they actually offer pretty much any size cone filter you can imagine
