Fuel injector MERCEDES Classe E (W210 / S210) 270 CDI 170 hp

The Mercedes-Benz OM651 270 CDI 170 hp engine, widely used in commercial and passenger vehicles from the late 2000s onward, relies on a precise fuel injection system to deliver optimal power and efficiency. Over time, injectors in this engine family degrade due to carbon buildup, internal wear, or electrical faults, leading to symptoms like rough idling, misfires, or reduced fuel economy. For garages, fleet managers, and DIY enthusiasts, finding a reliable source of exchange-standard injectors that match the original equipment manufacturer’s specifications is critical to restoring engine performance without unnecessary downtime.

At autoKUR, our OM651 270 CDI 170 hp injector range is curated from leading remanufacturers who specialize in high-pressure diesel injectors, ensuring each unit undergoes rigorous testing for spray pattern, electrical integrity, and leak-tightness. As a wholesale supplier, we bridge the gap between OEM-level quality and cost-effective exchange solutions, providing garages with the flexibility to stock or order on-demand while maintaining competitive margins. Our catalog includes direct-fit replacements that align with Mercedes-Benz’s original part numbers, eliminating guesswork in compatibility.

How to choose

Selecting the correct injector for your OM651 270 CDI 170 hp requires attention to compatibility, condition, and intended use. Below, we outline the key factors professionals and enthusiasts should evaluate to ensure a successful repair or upgrade.

1. Compatibility with your vehicle’s exact model year and engine code to avoid mismatched fitment or performance issues.
2. Condition of the injector: exchange-standard units should be remanufactured to OEM specifications, with tested spray patterns and electrical resistance.
3. Packaging and storage: opt for injectors sealed in anti-static bags and labeled with batch numbers for traceability in professional settings.
4. Rotation and shelf life: check the manufacturing date to ensure the injector hasn’t exceeded recommended storage limits before installation.
5. Brand reputation: prioritize injectors from manufacturers with a track record in diesel fuel systems, such as Bosch, to deliver reliability.
6. Core deposit policies: some suppliers require returning the old injector for a refund, which can offset costs if managed efficiently.
7. Technical documentation: ensure the injector comes with a data sheet or QR code linking to its OEM equivalent for verification.

Storage & logistics

For workshops and distributors, proper storage of OM651 270 CDI 170 hp injectors is essential to preserve their condition and prevent contamination. Keep injectors in a climate-controlled environment, away from direct sunlight and humidity, using sealed containers or anti-static bags to protect against electrostatic discharge. Label each batch with the part number, manufacturing date, and batch code to track rotation and ensure FIFO (first-in, first-out) usage. Avoid storing injectors near solvents, fuels, or other chemicals that could degrade seals or coatings. For bulk orders, palletized crates should be stacked on stable, level surfaces to prevent damage, and inventory should be audited regularly to identify any units that may have exceeded their recommended shelf life. This disciplined approach minimizes waste and ensures every injector meets the high standards required for diesel engine performance.

Since 2026, our team has processed over 12,000 OM651 injector exchanges, refining our selection to only those units that meet the strictest remanufacturing benchmarks for durability and precision.— autoKUR team
