Sinister Diesel Coolant Filtration System with Wix Filter for 2003-2007 Ford F-250/F-350 & Excursion (6.0L)

Fits 2003-2007 Ford F-250/F-350 Super Duty and 2003-2005 Ford Excursion (6.0L).

The 6.0L Powerstroke is notorious for cooling system issues caused by residual casting sand, metal shavings, and mineral deposits. This Sinister Diesel coolant filtration system is a bypass-style kit designed to capture these abrasive contaminants before they can damage your water pump bearings, clog your oil cooler, or compromise the small passages in your EGR cooler. By maintaining a cleaner cooling system, you ensure more efficient heat transfer and extend the service life of critical engine components.

Constructed for durability and ease of use, this kit features a filter boss CNC-machined from solid 6061 billet aluminum and finished in a signature Sinister Blue anodizing. The included high-strength silicone hoses are abrasion-resistant and feature a molded T-junction to eliminate potential points of failure. Installation is straightforward, utilizing a heavy-duty bracket that mounts to factory holes, requiring no drilling or permanent modification to your vehicle.
