I have had a K/N for 30K miles and every oil analysis I have done shows the silicon levels are low (less than half the universal averages). So I dont think it is letting much through in my case. The key is to oil and maintain it properly.

 

So nobody's tried the GReddy filter huh? I wanna give it a shot with a Z-Tube. Do you think it's yield the same thing as the pop-charger?
