Hey guys,my s4 has 115k.Im doubting my ko3s are going to last much longer. Will my car be more reliable if i went to ko4s, or just stuck in some ko3s with 44k on them? thanks guys.

Assuming you do the necessary preventative maintenance and don't do anything crazy.
My A6 2.7T has 116k on it and I beat the **** out of this car. Original K03's, MAF, TBB, Bi-pipe, etc.
If you're gonna pull the engine and swap the turbos, you might as well go K04.
