Fuel injector OPEL Insignia B Sports Tourer 2.0 CDTI 170 hp

The 2.0 CDTI 170 HP diesel engine, found in models like the Opel Insignia and Astra, demands precise fuel delivery to maintain performance and emissions compliance. This category gathers reconditioned fuel injectors designed to replace worn or faulty units, ensuring the engine runs smoothly without the expense of a new OEM part. Whether you’re a mechanic sourcing parts in bulk or a car owner restoring a vehicle, these injectors are engineered to match the original specifications of the 2.0 CDTI 170 HP motor.

This range is built around wholesale partnerships with leading remanufacturers, who restore injectors to a like-new condition by replacing internal components, recalibrating spray nozzles, and pressure-testing for leaks. The role of the wholesaler is to aggregate these high-quality parts, ensuring consistent availability and competitive pricing for independent garages and DIY enthusiasts alike.

How to choose

Selecting the right injector involves checking compatibility with your engine code, verifying the remanufacturing process, and ensuring the packaging meets your workshop’s storage needs.

1. Verify the engine code (e.g., Z20DTH) matches the injector’s application list to avoid misfires or fuel leaks after installation.
2. Prefer injectors with documented remanufacturing steps, including nozzle cleaning, armature replacement, and high-pressure testing for longevity.
3. Choose bulk packaging if you service multiple vehicles, as it reduces per-unit costs and simplifies inventory management in a professional setting.
4. Inspect the injector’s condition upon arrival: look for corrosion, damaged connectors, or missing seals that could compromise performance.
5. Opt for suppliers offering a core return policy, allowing you to offset costs by returning the old injector for recycling or credit.
6. Check the injector’s spray pattern consistency, as uneven distribution can lead to cylinder imbalance and premature wear.
7. Prioritize suppliers with transparent sourcing, ensuring parts are traceable to reputable remanufacturers rather than uncertified rebuilds.

Storage & logistics

Reconditioned injectors for the 2.0 CDTI 170 HP should be stored in a dry, temperature-controlled environment away from direct sunlight to prevent seal degradation. For garages, keeping injectors in their original packaging until installation avoids contamination from dust or moisture, while DIY users should handle parts with gloves to avoid skin oils affecting seals. Bulk orders benefit from organized shelving with first-in-first-out rotation to ensure parts are used before shelf life concerns arise, though no expiration date is imposed on these products.
