This system continuously filters small amounts of coolant, removing contaminants before they can cause expensive failures
-
Cleaner coolant means better heat transfer, longer component life, and fewer costly breakdowns
-
Designed as a bypass-style system, it filters efficiently without restricting coolant flow or risking overheating

Anodized billet aluminum construction and Sinister Blue finish give your engine bay a professional, high-performance appearance
Product Description
The Sinister Diesel Coolant Filtration Kit is one of the most effective upgrades you can make for your 7.3L Powerstroke. Even a new engine can circulate leftover casting sand, rust, and metal flakes through the coolant system—slowly clogging your oil cooler, heater core, and water pump. Over time, that contamination leads to overheating and expensive failures.
This kit solves the problem by adding a bypass-style filtration system that continuously cleans your coolant as the engine runs. The CNC-machined 6061 billet aluminum filter block mounts directly to existing factory holes for a clean, no-drill installation. It’s anodized in Sinister Blue for corrosion protection and durability.
Each kit includes a genuine WIX 24070 filter, known for its efficiency and reliability, along with pre-assembled multi-layer silicone hoses featuring crimped brass fittings for a professional, leak-free connection.
Installation is simple—most users can complete it in under two hours with basic hand tools. Once installed, you’ll enjoy cleaner coolant, lower maintenance costs, and extended engine life.

Q&A
What does this kit do?
It filters casting sand, rust, and metal shavings from your cooling system to protect the oil cooler, heater core, and water pump. Cleaner coolant keeps your 7.3 running cooler and more efficiently.
Why is it a bypass filter instead of inline?
The bypass system filters a small percentage of coolant at a time until all of it has passed through the filter. Inline systems can block flow if the filter clogs. With the Sinister Diesel bypass design, coolant continues to circulate even if the filter becomes full—no risk of overheating or engine damage.
What filter is included?
A genuine WIX 24070 spin-on coolant filter is included. It’s proven for high-flow, low-restriction performance and uses a standard 11/16-16 thread for easy replacement.
Does it change coolant chemistry?
No. The WIX filter is purely mechanical—it doesn’t add or remove any chemical additives and works perfectly with Extended Life Coolant (ELC).
What materials are used?
The filter block is CNC-machined from 6061 billet aluminum and anodized in Sinister Blue. The hoses are multi-layer high-temp silicone with pre-crimped, leak-proof fittings.
Is installation easy?
Yes. The mounting bracket uses existing factory holes—no drilling or cutting required. Everything you need for installation is included.
How long does installation take?
About 2 hours on average, depending on experience.
How often should the filter be replaced?
• First filter: 500 miles
• Second filter: 1,000 miles
• Third filter: 3,000 miles
• Then change with every oil filter service
What’s included in the kit?
• Billet aluminum filter block
• Anodized mounting bracket
• Pre-assembled silicone hoses
• Genuine WIX 24070 filter
