PRODUCT KNOWLEDGE

Understand this product

Filter Mount Assembly — BK309 belongs to the bypass-filtration equipment catalog. Compare its exact part identification with the system instructions before ordering, particularly when matching replacement fittings, hoses or elements.

APPLICATION & SELECTION

Bypass filtration and installation parts

Match the exact system, replacement element or fitting to the installed bypass assembly. A bypass component is not automatically a replacement for the engine’s full-flow filter.

No universal vehicle fitment is implied by this listing. Use the exact product or part number when checking application information.

Compatibility check

Confirm the kit model, hose size, fitting threads, mounting arrangement and replacement-element reference. Use the installation instructions for the complete assembly; this listing alone does not establish a safe installation.

Application status
Verify the exact equipment requirement

No product data bulletin was linked in the manufacturer listing reviewed. Use the official product information and equipment instructions for the current application details.

The manufacturer bulletin contains the detailed applications, test methods and any service limitations. A published typical test value is not a guarantee for every operating condition. “Recommended for” language should not be read as a claim of formal manufacturer approval.

MAINTENANCE NOTES

Use it as part of a complete service plan

Keep hoses protected from heat, abrasion and moving parts. Follow the system instructions for inspection and service. A bypass system does not independently establish a longer oil-change interval.
