Review GBR Fuel Injector Set More fits CAMRY ES250 ES300H NX450H RX350H

The **Genuine Toyota Part Number 845-12164S4 Fuel Injector Set** is a high-performance, precision-engineered component designed exclusively for Toyota s hybrid and non-hybrid models, including the **ES250, ES300H, NX450H, RX350H, and Camry (select generations)**. This meticulously crafted set features **four high-flow, cold-start capable fuel injectors**, each engineered to deliver optimal fuel atomization and distribution, ensuring efficient combustion, enhanced throttle response, and improved overall engine performance. Built to Toyota s rigorous OEM standards, these injectors incorporate **ceramic-coated nozzles** for superior durability and resistance to carbon buildup, while their **electromagnetic solenoids** provide precise fuel delivery with minimal lag, even under demanding driving conditions. The injectors are compatible with Toyota s **direct-injection systems**, offering consistent spray patterns and pressure regulation to prevent clogging or uneven fuel distribution, which is critical for maintaining the hybrid powertrain s efficiency and the non-hybrid engine s power output. Whether replacing worn injectors in a high-mileage vehicle or upgrading for performance tuning, this set ensures reliable operation, reduced emissions, and a smoother, more responsive driving experience. Backed by Toyota s quality assurance, these injectors are a direct-fit replacement, eliminating the need for modifications, and are ideal for both professional mechanics and DIY enthusiasts seeking a seamless upgrade.

### **Pros and Cons of Buying a Genuine OEM 845-12164S4 Fuel Injector Set for Toyota Models (ES250, ES300h, NX450h, RX350h, Camry)**

1. **Direct Fitment and Reliability** The 845-12164S4 is a genuine Toyota part, meaning it is designed specifically for the engine in your vehicle. This ensures proper fitment, compatibility with the fuel system, and adherence to Toyota s engineering standards, reducing the risk of leaks, clogs, or performance issues.

2. **High-Quality Materials** Toyota uses durable materials in its injectors, which are built to last longer than many aftermarket alternatives. This can extend the lifespan of your fuel system and improve overall engine efficiency.

3. **Better Fuel Efficiency and Performance** Properly functioning injectors ensure optimal fuel atomization, leading to better combustion, smoother acceleration, and improved fuel economy. If your engine is running poorly (e.g., rough idle, hesitation, or poor power), replacing faulty injectors can restore performance.

4. **Prevents Long-Term Damage** Clogged or failing injectors can lead to carbon buildup, fouled spark plugs, or even catalytic converter damage. Replacing them proactively can avoid costly repairs down the line.

5. **Warranty Coverage** Since this is a genuine Toyota part, it may come with Toyota s warranty (if purchased through an authorized dealer or Toyota-approved supplier), providing peace of mind against defects.

6. **Compatibility with Modern Fuel Systems** These injectors are designed for Toyota s direct-injection or port-injection systems (depending on the model), ensuring they work seamlessly with the engine s fuel pressure regulator and ECU.

7. **Easier Maintenance and Replacement** Because they are OEM, they are widely available, and mechanics familiar with Toyota vehicles can install them quickly and accurately.

---

1. **Higher Cost** Genuine Toyota injectors are significantly more expensive than aftermarket alternatives. A full set (typically 4-8 injectors, depending on the engine) can cost **$300 $800 **, depending on the model and where you purchase them.

2. **Potential for Overkill (If Only Some Injectors Are Bad)** If only one or two injectors are failing, replacing the entire set may be unnecessary. Diagnosing individual injector health (via a scan tool or pressure test) can save money if only a few need replacement.

3. **Installation Complexity** Fuel injectors require precise installation, including proper sealing, wiring, and calibration. If not installed correctly, they can leak fuel or fail to spray properly, leading to further issues.

4. **Depreciation Risk** If you re buying used or from a third-party seller, there s a risk of counterfeit or damaged parts. Always verify authenticity, especially if purchasing from non-Toyota sources.

5. **Alternative Solutions May Be Sufficient** If the injectors are only mildly clogged, cleaning them (via a professional injector cleaning service or additives like **Seafoam or CRC**) may restore performance at a fraction of the cost.

6. **Time-Consuming Replacement** Replacing injectors often requires removing the intake manifold, fuel rail, and possibly the throttle body, which can take **2 4 hours** of labor, depending on the model.

7. **Potential for ECU Issues** If the injectors are old, the engine control module (ECU) may need a **learn cycle** after replacement to recalibrate fuel delivery. Some drivers report minor drivability issues (e.g., slight hesitation) until the ECU adjusts.

### **Conclusion**

Buying a **genuine 845-12164S4 fuel injector set** for your Toyota (ES250, ES300h, NX450h, RX350h, or Camry) is the **best choice for long-term reliability and performance**, especially if your engine is exhibiting symptoms of failing injectors (e.g., rough idle, misfires, poor acceleration, or check engine lights). The upfront cost is justified by the **durability, compatibility, and potential to prevent costly engine damage**.

- **Injector Cleaning** (professional service or high-quality additives)

- **Aftermarket OEM-Equivalent Injectors** (brands like **Denso, Delphi, or Stanadyne** often match Toyota specs at a lower cost)

- **Partial Replacement** (if diagnostics confirm only 1 2 injectors are bad)

If you proceed with a full OEM replacement, **purchase from an authorized Toyota parts dealer or a reputable online retailer** (e.g., **Toyota Parts America, RockAuto, or Amazon with verified sellers**) to avoid counterfeits. Always have a **mechanic with Toyota experience** perform the installation to ensure proper sealing and calibration.

- **If your injectors are confirmed faulty and you want the most reliable fix Buy the genuine 845-12164S4 set and replace all injectors at once.**

- **If you re unsure or on a budget Get a diagnostic scan, try cleaning the injectors, or consider aftermarket alternatives.**

- **If you re replacing them yourself Ensure you have the right tools (torque wrench, fuel pressure gauge, O-ring lubricant) and follow Toyota s service manual procedures carefully.**

For most Toyota owners experiencing injector-related issues, **the OEM injectors are the safest long-term solution**, but weigh the cost against diagnostics to avoid unnecessary expenses.
