PROLONG ENGINE & OIL LIFE: Using Sinister Diesel Oil Filter & Coolant Filtration System you can prolong the life expectancy of your oil and engine. As time passes, the oil starts losing its quality due to contaminants coupled with dirty coolant that causes significant damage to your engine. Our Coolant Filtration System for Oil Filter & Coolant Filtration System minimizes contaminants in oil and filter coolant to increase the lifespan of your engine.

FOR FORD POWERSTROKE 2003-2007: This Coolant Filtration System Kit and oil filter kit is made specifically for FORD POWERSTROKE models between 2003-2007 to provide a precise installation without having to remove any engine parts or drill any new holes

PREMIUM GRADE CONSTRUCTION: To provide the finest oil filtration kit and coolant filtration kit we used the finest quality CNC machined billet 6061 aluminum to ensure long-term use to reliably bypass and filter small amounts of contaminants in the oil and coolant while to increase 6.0L Diesel engine lifespan.

Direct fit for the 2008-2010 Ford 6.4L Powerstroke

Filters solid particles from coolant and installs in under 45 minutes

Extends the life of your oil cooler, water pump, EGR cooler, and coolant

MADE TO LAST: 6.0 powerstroke coolant filter kit When it comes to the quality of our products, We dont make any exceptions! Our Coolant Filtration System Compatible with Ford 2003-2007 is made with long-term use in mind which is why we use CNC machined billet 6061 aluminum to ensure long-term use to reliably bypass and filter small amounts of coolant while minimizing the number of containments to increase engine lifespan.

INCREASE ENGINE LIFE: It is commonly known that Ford 6.0L engines have extra solid particles left over from casting the engine which can clog your trucks factory oil cooler, EGR cooler, and other critical engine components.

MADE TO FIT: The mounting bracket mounts a precision CNC-machined 6061 aluminum filter mount and coolant filter to the passenger side radiator support area, an ideal location for easily removing the filter. This 6.0L coolant filtration system is routed in parallel with the flow path of your coolant system and allows a small amount of coolant to be filtered with each pass.
