**Pros and Cons of Buying a Hitachi SX-2065 Fuel Injection Throttle Body for a 2006 2015 Nissan Armada 5.6L V8 Air**

### **Pros**

1. **Compatibility** The Hitachi SX-2065 is a direct replacement for the stock throttle body on the 5.6L V8 Nissan Armada (air injection model), ensuring proper fitment without modifications.

2. **Improved Performance** A high-quality throttle body like the Hitachi SX-2065 is designed for better airflow and throttle response, which can enhance engine performance, especially in applications where the stock unit may be restricted or worn.

3. **Durability** Hitachi components are known for their robust construction, often featuring stainless steel or high-grade plastics that resist wear, corrosion, and heat better than some aftermarket alternatives.

4. **Ease of Installation** Since it is a direct replacement, installation typically requires minimal effort, often just unplugging the wiring harness, removing the old unit, and securing the new one in place.

5. **Potential Fuel Efficiency Gains** A properly functioning throttle body ensures optimal fuel-air mixture, which can lead to slight improvements in fuel economy, particularly if the original unit was clogged or malfunctioning.

6. **Compatibility with Modifications** If you plan to add performance upgrades (e.g., ECU tuning, intake, or exhaust), a high-quality throttle body like this one can better handle increased airflow demands.

7. **Warranty and Support** Hitachi offers warranties on their products, and they are a reputable brand with available customer support for troubleshooting or replacements if issues arise.

### **Cons**

1. **Cost** The Hitachi SX-2065 is a premium throttle body, and while it is a quality product, it may be more expensive than generic or no-name alternatives. Pricing can vary depending on the seller and whether it comes with additional accessories (e.g., gaskets, wiring harness).

2. **Potential Overkill for Stock Applications** If your Armada is running stock with no performance modifications, the benefits of upgrading to this throttle body may be marginal. The stock unit could still function adequately for daily driving.

3. **ECU Tuning May Be Required** Some throttle bodies, even direct replacements, may require ECU tuning to optimize performance, especially if they have different airflow characteristics than the stock unit. This adds an extra cost and complexity.

4. **Installation Challenges** While generally straightforward, some users may encounter difficulties with wiring harness connections or securing the throttle body properly, particularly if they lack mechanical experience.

5. **Market Availability** High-quality throttle bodies like the Hitachi SX-2065 may not always be in stock at local auto parts stores, requiring online purchases, which could involve shipping delays or additional fees.

6. **No Significant Power Gains Without Supporting Mods** Upgrading just the throttle body will not dramatically increase horsepower or torque. Real performance gains typically require complementary upgrades (e.g., intake, exhaust, fuel system adjustments).

7. **Potential for Compatibility Issues** While the Hitachi SX-2065 is designed for your application, there is a small risk of minor fitment issues (e.g., wiring harness length, mounting bolt spacing) if the unit was previously damaged or if aftermarket modifications were made to the intake manifold.

### **Conclusion**

The Hitachi SX-2065 throttle body is a solid choice for a 2006 2015 Nissan Armada 5.6L V8 air injection model, particularly if you are looking to improve throttle response, airflow, or prepare the vehicle for future performance modifications. Its durability, compatibility, and reputation for quality make it a reliable upgrade. However, if your primary goal is basic reliability and you are not planning performance enhancements, the stock throttle body may suffice without the added cost.

### **Recommendation**

- You are adding performance modifications (e.g., ECU tuning, intake, exhaust) and want a high-quality throttle body to support those upgrades.

- Your stock throttle body is worn, clogged, or malfunctioning, and you want a direct replacement with improved durability.

- You prioritize long-term reliability and are willing to invest in a premium component.

- Your Armada is running stock with no performance goals, as the benefits may not justify the cost.

- You are on a tight budget and can find a high-quality generic throttle body at a significantly lower price.

- You lack the mechanical skill or tools to install it properly, as improper installation could lead to leaks or performance issues.

For most performance-oriented owners of the 5.6L Armada, the Hitachi SX-2065 is a worthwhile investment that will pay off in improved throttle response and longevity. Pair it with an ECU tune if you plan to push the engine further.
