Features:
Your factory cooling system does not include a dedicated coolant filter. That means casting sand, rust, sediment, metal shavings, and other contaminants can continue circulating through the engine as the coolant flows.
Over time, these particles can collect in small coolant passages, contribute to heater core restrictions, and accelerate wear on other cooling system components.
Our bypass coolant filtration system addresses this problem by continuously routing a small amount of coolant through a dedicated WIX spin-on filter while the engine is running. The filter captures contaminants as coolant circulates through the bypass circuit, helping keep the entire cooling system cleaner over time.
Because the filter operates independently of the primary coolant flow path, it does not place a restrictive filter directly in the engine's main cooling circuit.
For 2013–2018 Ram 2500 and 3500 owners, one of the biggest advantages is helping prevent heater core clogging before it turns into a costly, time-consuming dashboard removal and repair.

Help Prevent a Clogged Heater Core Before It Becomes a Costly Repair:
One of the most frustrating cooling system problems a Ram 2500 or 3500 Cummins owner can experience is a clogged heater core. Contaminants circulating through the coolant can gradually accumulate inside the heater core's narrow passages, restricting coolant flow and leaving you with weak cabin heat or no heat at all.
The repair can be expensive. On many Ram trucks, replacing the heater core requires extensive dashboard disassembly, turning a relatively small cooling system component into a repair that can cost thousands of dollars in parts and labor.
The Sinister Diesel Coolant Filtration System is designed to help prevent that problem by removing harmful contaminants from your cooling system before they have a chance to accumulate inside the heater core.
Built for Your Cummins. Designed for Long-Term Protection.:
The system features a precision CNC-machined 6061 billet aluminum filter block finished in signature Sinister Blue, a vehicle-specific mounting bracket, and reinforced silicone hoses designed for demanding underhood conditions.
Whether you use your Ram for daily driving, heavy towing, hauling, or work, keeping contaminants out of the coolant is a practical way to help protect your heater core and other expensive cooling system components.
