Warning!! There are copies of the FLO Oil Filters on the market that are manufactured in China… some cost more, some cost less. If your made in China filter falls apart or color fades DO NOT assume a FLO Oil Filter will. Watch video belowÂ

Cleanable and Reusable
Superior Filtration: 10 Micron Nominal rating, 35 microns “absolute rating” (one-pass test). This is much better than multiple-pass rated paper filters, especially 5 micron stated filters that bypass all filtration regularly. Additionally, the 3 super strength magnets on the FLO Oil Filter will trap particles as small as a single micron.

Pays for Itself: Reduces long-term costs by eliminating the need for disposable filters.
Superior Filtration
The FLO Oil Filter should be the last oil filter you’ll ever need! Made from laser-cut, medical-grade 304 stainless steel micronic filter cloth, it provides up to 200% more filter area in many cases. This filter captures particles down to 35 microns (absolute rating, one-pass test), which is about three times better than many good paper or brass filters.
Unlike glued paper filters, the FLO Oil Filter pleat seam is welded, making it capable of withstanding temperatures up to 600°F.
Consistent Flow Under All Conditions
The FLO Oil Filter maintains a consistent flow, even under extreme conditions such as high heat, the presence of water, or cold starts. Paper filters can struggle in these conditions, often causing the bypass valve to open and allow unfiltered oil into the engine. The FLO Oil Filter ensures that doesn’t happen, giving you superior protection under any conditions.
This advanced filter technology is widely used across auto racing (NASCAR, Indy-type cars, Formula 1), as well as in the aerospace industry, where filtration is critical for high-performance machinery.
Environmental Impact
In addition to its performance benefits, the FLO Oil Filter helps keep landfills free of old, used filters, contributing to a cleaner environment.
Cleaning Instructions
Note the original filter position to ensure correct installation.
Clean the filter at each oil change using solvent, contact cleaner, kerosene, or any degreasing agent—even common dish soap works.
Blow air through the filter from the inside out to remove any small particles or cleaning agents.
Lubricate rubber parts with clean oil before installation to ensure a proper seal.
Torque the filter to 15 ft lbs
