Sinister Diesel 99-03 Ford 7.3L Powerstroke Coolant Filtration System w/ Wix Filter

The CNC machined billet 6061 aluminum filter block in this Sinister Diesel coolant filtration system is anodized in a distinctive Sinister Blue. This well-built block attaches to a supplied bracket that uses factory mounting holes, meaning no drilling is required for installation on your 1999-2003 Ford 7.3L Powerstroke. Keeping your coolant clean is crucial for the longevity of your engine's water pump, EGR cooler, and oil cooler, as it removes harmful casting sand and metal shavings.

This kit bypasses and filters a small amount of your engine's coolant while it's running, utilizing a genuine WIX coolant filter. The filter block features two threaded inlet ports and one outlet port, and all necessary fittings are included for a straightforward installation. The silicone hoses come pre-assembled with leak-proof connections that have been factory tested. We recommend replacing the first filter after 500 miles, the next two filters at 3,000 miles each, and then annually thereafter.
