What parts are included and how do they match OEM references?

The kit contains the three filter elements required for a standard service: oil, fuel, and air. Each component replaces the corresponding Thermo King reference number so you don’t need to source separate parts.

• 1 × 11-9959 — oil filter element sized for Thermo King/Yanmar installations.
• 1 × 11-9965 — fuel filter element compatible with Thermo King fuel systems.
• 1 × 11-9955 — air intake filter element for refrigerated unit engines.
• Includes necessary accessories for a straightforward swap; packaged as a single PM kit.

How simple is installation and what should I prepare?

Installation is intended to be a direct swap for the original parts, so routine hand tools and basic workshop procedures are typically all that’s needed. Follow Thermo King service guidance and standard safety practices when replacing filters.

• Direct-fit parts minimize modifications or adaptors during replacement.
• Prepare common tools: wrenches, drain pans, rags, and disposal containers for used filters.
• Inspect gaskets and seals on removal; replace if damaged to maintain sealing integrity.

Why choose this GaeaAuto kit over buying parts separately?

Buying a matched PM kit reduces ordering errors and ensures the three critical filters are replaced together, maintaining balanced protection for the engine and fuel system. GaeaAuto emphasizes quality materials and manufacturing that meet or surpass OEM standards.

• Cost and time savings compared with sourcing each filter individually.
• Packaged compatibility reduces risk of mismatched elements or incorrect sizes.
• Quality control and materials designed to meet or exceed original equipment performance.
