Product Overview
The Sinister Diesel Coolant Filtration Kit for the 6.0 Powerstroke has been fully updated—delivering improved reliability, cleaner installation, and long-term durability.
This is the same proven system trusted by thousands of 6.0 owners, now upgraded with our latest design improvements. The original “tombstone” style filter head has officially been retired and is no longer available. In its place is our new filter head design, built for better strength, consistency, and overall performance.
The hose system has also been completely refined with a one-piece molded design and upgraded internal connections. These improvements eliminate common weak points found in older multi-piece setups and provide a more secure, dependable system built to last.
The 6.0 Powerstroke is known for coolant contamination—casting sand, rust, and debris circulating through the system from the factory and over time. This kit continuously filters those contaminants out while the engine runs, helping prevent oil cooler blockage, EGR cooler failure, and premature water pump wear.
Installation remains straightforward with a factory-style mounting bracket and no cutting or drilling required. Maintenance is simple with an easy spin-on WIX filter.
This isn’t just a replacement—it’s a direct evolution of the original, built to perform better in every way.

FAQ
What does this kit do for my 6.0 Powerstroke?
It filters out casting sand, rust, and metal debris from your coolant. Removing these contaminants helps prevent oil cooler and EGR cooler failures while protecting your water pump and maintaining proper coolant flow.
Why is it a bypass system instead of inline?
A bypass system filters a portion of coolant at a time while the engine runs, eventually cleaning the entire system without restricting flow. Inline filters can become a restriction if clogged, but a bypass design keeps coolant moving safely at all times.
What filter is included and does it affect coolant chemistry?
This kit includes a genuine WIX 24070 coolant filter. It’s a high-flow, non-chemical filter that does not alter coolant chemistry and is safe for use with ELC or standard coolant.
How often should the filter be replaced?
• First filter: 500 miles
• Second filter: 1,000 miles
• Third filter: 3,000 miles
• After that: replace with every oil filter service
How long does installation take and what’s involved?
Installation typically takes around 2 hours using basic hand tools. The kit mounts to factory locations with no cutting or drilling required.
What’s included in the kit?
