OE: BYDSEM-1117010 Fuel Filter Assembly for BYD Song / Qin | BYD

The OE: BYDSEM-1117010 fuel filter assembly is designed for gasoline-powered BYD Song and BYD Qin models.
It provides stable filtration for fuel-injection systems that require clean and consistent fuel flow.
This filter removes small contaminants before fuel reaches the injectors, supporting smooth acceleration and steady combustion in both urban and highway driving.
Its design helps maintain predictable performance for drivers who rely on these models for daily use.

Compatibility

This fuel filter assembly fits BYD Song and BYD Qin gasoline platforms equipped with:

• 1.5L MPI gasoline engine

• 1.5T turbocharged gasoline engine

These engines require accurate injection control supported by clean fuel flow.
The filter works in the main fuel line and operates as the primary filtration unit before the injection rail.
Its housing and connector layout follow OE specifications for direct installation.
The filter is suitable for markets where fuel quality can vary, supporting a wide range of operating conditions.

Filtration / Material / Mechanical Design

The filter uses a multi-layer synthetic filtration medium engineered to capture fine particles without restricting fuel flow.
Its metal housing provides durability under pressure changes that occur during high-speed driving and rapid acceleration.
Internal flow channels help stabilize fuel delivery and maintain consistent pressure at the injection rail.
OE-grade seals offer secure installation and prevent air intrusion.
The unit is designed to operate reliably in warm climates, dense traffic environments, and regions with varied gasoline quality.

Flow Stability & Engine Protection

Clean filtration supports smooth throttle response and predictable torque delivery.
The filter helps maintain stable idling and reliable cold-start behavior.
Consistent fuel purity reduces strain on injectors and supports long-term engine reliability.
By controlling fine contaminants, the assembly helps optimize fuel combustion and reduce deposit formation within the system.

Interchangeable OE Numbers (Cross-Reference)

• BYDSEM-1117011

• BYD1117010-SM

• BYD1117010-00

Maintenance Replacement (Official Interval)

For BYD gasoline platforms, the recommended interval is every 20,000–30,000 km depending on regional fuel conditions.
Shorter intervals may be appropriate in areas with inconsistent gasoline quality.
Technicians should inspect the unit during routine servicing for signs of contamination.
