TMLGB Freightliner & Cummins Filter Kit 4‑Piece — AF27879 FS19915 PF9908 LF17511 OEM‑equivalent protection for DD13/DD15/ISX15

TMLGB AF27879 FS19915 PF9908 LF17511 Filter Kit is a complete air, oil and fuel filtration set designed to protect Freightliner Cascadia DD13/DD15/DD16 and Cummins ISX12/ISX15 engines with OEM-equivalent performance.

This four-piece kit bundles an air filter, oil filter, fuel filter and fuel/water separator engineered to meet or match original equipment specifications. Delivered as a matched set, the components are manufactured to strict tolerances and factory-tested so you can replace multiple service items in one stop. The kit fits a wide range of Freightliner models including Cascadia and Coronado series (model years 2008–2019), helping maintain clean airflow, oil circulation and contaminant-free fuel under heavy-duty conditions.

How does this kit keep my engine running reliably?

The filters work together to block particles, water and debris before they can damage critical engine systems. Clean air improves combustion efficiency, a quality oil filter protects internal bearings and passages, and the fuel side prevents contaminants from clogging injectors. Together they reduce wear and maintain steady engine performance across long haul and vocational applications.

• Air filter AF27879 captures dust and particulates to protect cylinders and turbochargers.
• Oil filter LF17511 maintains lubricating oil cleanliness for bearings and camshafts.
• Fuel filter PF9908 removes fine particles from fuel before injectors.
• Fuel/water separator FS19915 removes water and coarse contaminants to prevent injection system damage.

Will these parts fit my Freightliner or Cummins engine?

The kit is designed for compatibility with Freightliner Cascadia DD13, DD15 and DD16 engines and many Coronado/M2 models from 2008–2019. It also fits Cummins ISX12 and ISX15 series engines that use the listed filter numbers. Always confirm fitment by cross-referencing your OEM part numbers or your vehicle’s service manual before ordering.

• Compatible models: Freightliner Cascadia, Coronado, M2 112 and related chassis.
• Engine series coverage: DD13, DD15, DD16 and Cummins ISX12/ISX15.
• Replacement OE references included for quick verification (e.g., AF56500, A4720921205).

What are the installation and maintenance benefits of this matched set?

Providing all four filters in one package simplifies scheduled maintenance and cuts downtime by reducing parts procurement steps. Components are built for straightforward replacement — the fuel/water separator and fuel filter are designed for fast servicing, while the air and oil filters follow common service procedures for heavy-duty trucks. Using a matched set reduces the risk of mixing filter efficiencies or brands that might not perform together.

• One-stop kit reduces ordering errors and service downtime.
• Filters designed for fast, familiar replacement during routine service intervals.
• Manufactured to OEM-like tolerances and factory-tested for reliability.

How does this kit protect against fuel contamination and water?

The included fuel/water separator separates free water and drains it away before the fuel reaches the final filter, while the inline fuel filter captures remaining particulates. This staged approach prevents water and debris from reaching high-pressure injection components, prolonging injector life and maintaining fuel system efficiency.

• FS19915 removes free water and prevents emulsified moisture from moving downstream.
• PF9908 provides final particulate filtration ahead of the injection system.
• Combined design reduces injector clogs and corrosion risks.

Who is this for? This TMLGB filter kit is intended for fleet managers, owner-operators and maintenance technicians who service Freightliner Cascadia and related Freightliner/Cummins heavy-duty diesel engines. It suits anyone seeking a single-purchase solution for scheduled maintenance, roadside service kits, or preventative replacements to keep trucks performing reliably on long hauls and heavy-duty applications.
