Review CARDONE NEW Fuel Injection Throttle Body Toyota 3.5l V6 Air Rq fits AVALON 2005–2018

The **Cardone SX-A706 Fuel Injection Throttle Body** is a high-performance, direct-fit replacement designed specifically for the **2005 2018 Toyota Avalon** equipped with the **3.5L V6 engine (Air RQ)** a model known for its smooth yet underwhelming stock throttle response. Engineered to enhance airflow, throttle response, and overall engine efficiency, this throttle body is crafted from durable **aluminum alloy**, ensuring a lightweight yet robust construction that minimizes weight while maximizing performance. Unlike generic aftermarket alternatives, the SX-A706 is meticulously calibrated to match the precise airflow requirements of the Avalon s **Multi-Port Fuel Injection (MPFI) system**, eliminating common issues like stalling, hesitation, or poor throttle progression that can plague stock throttle bodies over time. Its **precision-machined internal passages** and **optimized venturi design** promote smoother airflow, reducing turbulence and improving throttle response, which is particularly noticeable during acceleration, cruising, and under load. The throttle body features a **sealed, high-quality gasket system** to prevent leaks and ensure a secure fit, while its **direct-fit design** eliminates the need for modifications, making installation straightforward for both DIY enthusiasts and professional mechanics. Whether you're looking to restore stock-like performance after a rebuild, upgrade from a worn-out OEM unit, or simply enhance the driving dynamics of your Avalon, the Cardone SX-A706 delivers a reliable, high-quality solution that balances performance, durability, and ease of installation. Built to meet or exceed OEM specifications, this throttle body is an ideal choice for those seeking a cost-effective yet effective upgrade that keeps power delivery crisp and responsive without the complexity of more aggressive modifications.

### Pros and Cons of buying a Cardone SX-A706 Fuel Injection Throttle Body for a 2005-2018 Toyota Avalon (3.5L V6, Air RQ)

1. **Improved Performance** The SX-A706 is designed to enhance throttle response and power delivery by replacing the stock throttle body with a high-flow unit. This can lead to quicker acceleration, especially in stop-and-go traffic or when passing.

2. **Better Fuel Economy (Under Certain Conditions)** Some drivers report slight improvements in fuel efficiency due to optimized airflow and fuel delivery, particularly when paired with a tuned ECU or performance chip.

3. **Easier Installation** Cardone products are known for straightforward installation, often requiring minimal modifications. The SX-A706 is a direct bolt-on replacement, meaning no major wiring or plumbing changes are typically needed.

4. **Compatibility with Performance Upgrades** If you plan to add a turbocharger, supercharger, or other power-enhancing modifications later, a high-flow throttle body like this one can help prevent airflow restrictions.

5. **Durability** Cardone components are generally built to last, with high-quality materials that resist corrosion and wear over time.

6. **OEM-Like Appearance** The throttle body retains a stock-like look, making it a subtle upgrade rather than an overt modification.

7. **Wider Throttle Range** The SX-A706 allows for smoother and more linear throttle response, reducing the "flat spot" some stock throttle bodies exhibit.

---

1. **ECU Tuning Required for Full Benefits** While the throttle body itself improves airflow, the engine control unit (ECU) may need reprogramming (via a chip, flash tune, or standalone ECU) to fully optimize fuel delivery and prevent stumbling or rough idle. Without tuning, performance gains may be minimal.

2. **Potential for Rough Idle or Stumbling** If the ECU isn t updated, the larger throttle body can cause fuel-air mixture imbalances, leading to a rough idle, hesitation, or even stalling, especially at low RPMs.

3. **Cost of Additional Modifications** To realize the full potential of the SX-A706, you may need to invest in an ECU tune (often $100 $300 ), which adds to the overall expense. Some users also opt for a high-flow intake or exhaust to complement the throttle body.

4. **Limited Power Gains Without Further Upgrades** The throttle body alone won t significantly increase horsepower or torque. For meaningful power improvements, you d need additional modifications like a turbo, intercooler, or camshaft upgrade.

5. **Potential for Increased Oil Consumption** Some high-flow throttle bodies can contribute to slightly higher oil consumption, particularly if the engine is already running lean or if the valve seals are worn.

6. **Warranty Concerns** Installing aftermarket parts like this throttle body may void certain aspects of the Toyota warranty, especially if the modification is deemed "non-conforming" by the manufacturer.

7. **Learning Curve for Tuning** If you choose to tune the ECU yourself (e.g., with a chip or standalone unit), there s a risk of improper calibration leading to drivability issues or engine damage if not done correctly.

The Cardone SX-A706 is a solid choice for Toyota Avalon owners looking to enhance throttle response and airflow without a full engine rebuild. It s a relatively simple and cost-effective modification that can make the car feel more responsive, especially in daily driving scenarios. However, its effectiveness is heavily dependent on proper ECU tuning, which adds to the cost and complexity.

If you re primarily looking for a subtle performance upgrade with minimal hassle and don t plan to push the engine aggressively, the SX-A706 is a worthwhile investment. For those aiming for significant power gains, it should be paired with additional upgrades like a tune, intake, or exhaust.

---

- You want smoother throttle response and better airflow for daily driving.

- You re willing to invest in an ECU tune to unlock its full potential.

- You plan to add other performance modifications (e.g., intake, exhaust) in the future.

- You prefer a bolt-on upgrade that s easy to install.

- You re not prepared to tune the ECU, as the throttle body alone won t deliver noticeable performance gains.

- You re on a tight budget, as the cost of tuning may outweigh the benefits.

- You re looking for a dramatic power increase, as this part alone won t provide significant horsepower gains.

- You re concerned about warranty voids or potential drivability issues without proper tuning.

**Final Verdict:** The Cardone SX-A706 is a practical upgrade for Toyota Avalon owners who want improved throttle feel and airflow, provided they commit to tuning the ECU. For those seeking a more substantial performance boost, it should be part of a broader modification plan.
