AMSOIL BE90 / EaBP90 Bypass Oil Filter (EABP90-EA)

AMSOIL BE90 / EaBP90 Bypass Oil Filter EABP90-EA

The AMSOIL BE90 (now superseded by the EaBP90 / EABP90-EA) is a high-efficiency bypass oil filter designed for compatible remote bypass-filtration systems. Unlike the engines primary full-flow filter, it processes a smaller portion of the circulating oil at a time, removing fine contaminants and soot down to approximately 2 microns far finer than a standard full-flow filter.

Note: The BE90 designation has been replaced by EaBP90 (product code EABP90-EA). This listing covers both the legacy BE90 and its current equivalent.

Important: This is a bypass filter only it must not be installed in place of the engines standard full-flow oil filter. It is designed exclusively for use with a compatible bypass-filter head and remote-filtration system.

Key Features

• High-efficiency bypass oil filter
• Fine-particle filtration down to approximately 2 microns
• Removes minute dirt particles and soot not captured by the full-flow filter
• Operates alongside the engines full-flow oil filter
• Processes approximately 10% of oil-pump capacity at a time
• Continuously cycles oil through the bypass system
• Increased contaminant-holding capacity
• Helps improve oil cleanliness and cooling
• Adds fluid capacity to the lubrication system
• Suitable for compatible gasoline and diesel bypass systems
• Current AMSOIL product code: EABP90-EA
• Legacy product designation: BE90 / BE-90

System Compatibility

The BE90/EaBP90 is intended for compatible AMSOIL single-remote, dual-remote, and Dual-Gard bypass-filtration systems designed to use the EaBP90 filter size. Compatibility depends on the installed bypass-filter head, mounting thread, hose arrangement, and available installation clearance.

Fitment Notice

Confirm the number on the existing bypass filter and identify the installed remote-filter system before ordering. A filter with a similar outside size or mounting thread is not automatically compatible with the systems flow restriction and filtration requirements. The BE90/EaBP90 must only be installed on a filter head designed for bypass filtration never in place of a normal full-flow engine oil filter.

Service Interval

AMSOIL lists the maximum EaBP90 service interval as up to 60,000 miles, 600 operating hours, or two years whichever occurs first. Earlier replacement may be appropriate when oil analysis indicates excessive contamination, after internal engine damage, or when the lubrication system has been exposed to coolant, fuel, water, or heavy soot contamination.

Installation Notes

Shut down the engine and allow the lubrication system to cool before servicing the bypass filter. Position a drain container beneath the filter and remove it according to the bypass-system manufacturers instructions. Clean the filter-head sealing surface and confirm the old gasket has been removed. Lubricate the new gasket with clean engine oil and tighten to AMSOILs specification. After installation: start the engine and allow oil to circulate, inspect the filter head, hoses, and fittings for leakage, shut down and check the oil level, add oil as required to account for the new filters capacity, then recheck after the engine reaches operating temperature.

Parts Desk Insights

The BE90/EaBP90 is a bypass filter, not a standard engine oil filter the most common mistake is matching it by size or thread and installing a full-flow filter in its place. Confirming the remote bypass-system model first protects both filtration performance and oil flow. If youre sourcing this to replace an existing BE90 in a legacy installation, the current EABP90-EA is the direct replacement and should be ordered by that part number going forward.
