About this category
The Toyota Aygo’s compact 1.0-liter 1KR-FE engine demands precision fuel delivery, and when injectors fail, performance drops sharply. This category covers remanufactured injectors designed for standard exchange, offering a cost-effective alternative to new parts while maintaining OEM-level accuracy. Whether you’re a mechanic sourcing bulk stock or a driver restoring a daily commuter, these components address common failure symptoms like misfires, rough idling, or fuel leaks.
Our injector range is built around verified OEM references, ensuring each unit undergoes rigorous remanufacturing to restore factory tolerances. Suppliers are selected for their adherence to consistent quality standards, providing garages and private owners with reliable replacements that integrate seamlessly into existing systems without requiring modifications.

How to choose
Selecting the right injector involves balancing several factors, from OEM compatibility to packaging size and supplier reliability. Below, we outline key criteria to guide your decision.
- Verify the injector’s OEM part number matches your Aygo’s engine code, ensuring seamless fitment and avoiding costly installation errors or performance mismatches.
- Prioritize units with clear remanufacturing documentation, as this indicates adherence to quality control processes and reduces the risk of premature failure.
- Consider bulk packaging if you’re a professional, as case or pallet orders streamline inventory management and reduce per-unit costs for high-volume replacements.
- Check for supplier certifications or traceability systems, which provide confidence in the injector’s origin and remanufacturing standards.
- Assess the injector’s condition upon arrival, looking for signs of proper storage and handling to prevent contamination or damage before installation.
- For DIY users, opt for injectors with detailed compatibility charts, simplifying the selection process and reducing the need for additional research.
- Evaluate the injector’s warranty terms, as longer coverage periods often reflect the supplier’s confidence in their remanufacturing process and component durability.
Storage & logistics
Professional garages should store remanufactured injectors in climate-controlled environments, away from moisture and direct sunlight, to preserve their condition. Units should be kept in original packaging until installation to prevent contamination, and inventory should follow a first-in-first-out rotation to ensure freshness. For bulk orders, palletized storage with clear labeling minimizes handling errors and streamlines order fulfillment, while single-unit sales benefit from individual protective wrapping to maintain integrity during transit.
Since 2026, we’ve supplied thousands of remanufactured injectors to garages across Europe, consistently meeting demand for OEM-compatible replacements that restore engine performance without the premium of new parts.— autoKUR team
