Description:
The Sinister Diesel Bypass Oil Filter System is the ultimate upgrade for your 6.7L Cummins. Factory filters only do part of the job—fine debris keeps circulating and slowly damages your engine. This system adds a secondary Amsoil 2-micron filter that removes what the stock filter misses, giving you cleaner oil, better protection, and longer engine life. Built with CNC-machined aluminum, braided stainless lines, and backed by Sinister’s reputation, this is an investment in long-term reliability.
