Product Description
The Sinister Diesel Bypass Oil Filter System is the ultimate protection upgrade for your 6.7L Cummins. The factory oil filter only captures larger particles, but microscopic debris continues to circulate and slowly eats away at critical engine parts. Our system fixes that by adding an Amsoil EaBP100 2-micron bypass filter, which removes the ultra-fine contaminants your stock filter can’t. The result? Cleaner oil, better protection, and longer engine life.
Built with Sinister Diesel’s CNC-machined billet oil cap and filter block, this system is as tough as your Cummins. Stainless braided lines with AN fittings ensure durability and leak-free performance. The kit installs easily with pre-made lines, bracket, and all required hardware—no custom fabrication needed.
Fitment Note: Not compatible with dual alternator or dual radiator setups. Some aftermarket grid heater kits require a slight modification to the corner of our mounting bracket.

Q&A
Q: How does a bypass oil filter system work?
A: Unlike the factory full-flow filter, a bypass filter diverts a small portion of oil through a high-efficiency secondary filter, removing much finer particles (down to 2 microns). This keeps the oil cleaner for longer without restricting flow to the engine.
Q: How often should the Amsoil EaBP100 bypass filter be replaced?
A: We recommend replacing the bypass filter every 15,000 miles or once a year—whichever comes first. This ensures maximum filtration efficiency and continued engine protection.
Q: Do I still need to replace my factory oil filter?
A: Yes. The bypass system works alongside your stock oil filter. Replace your OEM oil filter according to your regular service interval.
Q: Will this system extend my oil change intervals?
A: Yes, cleaner oil allows for extended drain intervals when paired with oil analysis testing. However, always follow manufacturer guidelines or consult your oil supplier before extending service intervals.
Q: Does this kit require any permanent modifications?
A: No. The system installs cleanly using pre-made lines and brackets that utilize existing factory points. No cutting or drilling is required.
Q: Is this compatible with aftermarket grid heaters or dual alternators?
A: It is not compatible with dual alternator or dual radiator setups. Some grid heater kits may require a small corner modification on the mounting bracket for clearance.
Q: What makes this system better than other bypass kits?
A: The Sinister Diesel kit combines high-efficiency Amsoil filtration with CNC-machined billet aluminum components, stainless steel braided lines, and factory-fit hardware for a precise, leak-free installation that lasts.
