Sinister Diesel20-21 GM Duramax L5P 6.6L Coolant Filtration System (W/ Wix)

Add years of life to your L5P Duramax diesel engine with this Water Coolant Filtration System with a Wix filter. Removing contaminates such as the casting sand and metal shavings left over from the manufacturing process means your water pump, EGR cooler and engine oil cooler will all last longer. This kit is designed to bypass and filter small amounts of coolant while your Duramax engine is running. The CNC machined billet 6061 aluminum anodized construction filter head attaches to supplied frame bracket. The filter boss includes 2 threaded inlet ports and 1 outlet port. This coolant bypass kit includes all fittings needed for installation. We recommend replacement of the first filter at 500 miles. Replacement of the second and third filters is at 3,000 miles each. After 3 filter changes, replacement can be done once a year. The silicone hose fittings are pre-assembled for simple, leak-proof connections and are factory tested at twice the recommended radiator cap pressure.
*This item will not fit trucks that have dual alternators*.
