---

### **Pros of Buying This Part**

1. **Direct OEM Fitment**

- The **4349-24** is a **direct replacement** for the stock accelerator pedal in the **2005 2007 Toyota Avalon** (and some Lexus models like the LS430).

- It matches the **exact dimensions, mounting points, and wiring** of the original part, ensuring a seamless installation without modifications.

2. **High-Quality Material**

- Toyota uses **durable plastic and metal components** in their accelerator pedals, which are designed to withstand frequent use.

- The pedal is **reinforced** to prevent excessive wear, especially in aggressive drivers.

3. **Compatibility with Aftermarket Pedals**

- If you plan to install an **aftermarket performance pedal** (e.g., a **stainless steel or carbon fiber pedal**), this OEM part serves as a **solid base** before modification.

- Some aftermarket pedals require the **same mounting points**, making this a good starting point.

4. **Widely Available & Affordable**

- As an **OEM part**, it is **readily available** from Toyota dealerships, auto parts stores (AutoZone, RockAuto, Amazon), and online marketplaces.

- Pricing is **competitive** compared to aftermarket alternatives, typically ranging from **$30 $80** depending on the source.

5. **Reliability & Longevity**

- Toyota parts are known for **long-lasting performance** under normal driving conditions.

- The **return spring and pedal mechanism** are designed to reduce pedal drift, improving throttle response over time.

6. **Easy Installation**

- The pedal is **straightforward to replace**, requiring only basic tools (screwdriver, socket set).

- No wiring changes are needed unless the pedal has integrated sensors (unlikely in this model).

7. **Supports Original Functionality**

- Unlike some aftermarket pedals that may alter **throttle response curves**, this OEM part maintains the **stock behavior** of the Avalon s engine management system.

---

### **Cons of Buying This Part**

1. **Potential for Wear in Older Vehicles**

- If the **original pedal was already worn** (e.g., from a previous owner or aggressive driving), replacing just the pedal may not fully resolve **throttle drift or sticking**.

- The **return spring** could also be degraded, requiring replacement if symptoms persist.

2. **Limited Customization Options**

- **Adjustable travel** (shorter/faster pedal movement).

- **Stainless steel or carbon fiber construction** (lighter weight).

- **Custom throttle response curves** (some aftermarket pedals allow for smoother or sharper acceleration).

- If you want **tuning or performance enhancements**, you may need to modify or replace it later.

3. **Possible Counterfeit or Low-Quality Replacements**

- **Fake or mismatched parts** (wrong year/model fitment).

- **Weak springs or poorly molded plastic**, leading to premature failure.

- **Recommendation:** Buy from **authorized Toyota dealers, RockAuto, or reputable online retailers** with return policies.

4. **No Integrated Throttle Position Sensor (TPS) in This Model**

- The **546.T0100 pedal** (part #4349-24) is a **mechanical pedal only** it does **not** include the **throttle position sensor (TPS)**.

- If the **TPS is faulty**, replacing just the pedal will **not fix throttle issues**.

- You may need to **separately purchase the TPS** (part #23210-30010 or equivalent) if symptoms like **poor idle or stalling** persist.

5. **Potential for Pedal Binding or Stiffness**

- Some owners report that **OEM pedals can become stiff** over time, especially if the **pedal pivot bushings wear out**.

- If this happens, you may need to **lubricate the pedal mechanism** or replace the **bushings** (separate part #s may apply).

6. **No Direct Benefits for Engine Performance**

- Unlike **performance pedals**, this part **does not improve acceleration, fuel efficiency, or engine response**.

- **ECU tuning** (e.g., APEXi, Haltech).

- **Performance pedals with adjustable travel**.

- **Upgraded throttle bodies or intake systems**.

7. **Environmental & Durability Concerns (Plastic Pedal)**

- The **plastic construction** can **crack or deform** under extreme heat or physical stress (e.g., dropping the pedal).

- While rare, this could lead to **premature failure** if the vehicle is used in harsh conditions.

---

- You want a **reliable, stock-fitment part** without modification.

### **Recommendation & Best Practices**

1. **Verify the Exact Part Number & Year Fitment**

- **RockAuto** (reliable, good return policy).

3. **Inspect the Pedal Before Installation**

- **Cracks or deformities** in the plastic.

- **Stiffness or binding** in the pivot points.

- If the pedal feels **loose or damaged**, consider replacing the **pedal bushings** (part #s may vary).

4. **Consider a Pedal Rebuild Kit if Symptoms Persist**

- A **pedal rebuild kit** (e.g., from **Toyota or aftermarket brands like Mann Filter**) can restore smooth operation.

5. **Combine with TPS Replacement if Needed**

- If you have **throttle-related issues (idling problems, stalling, rough acceleration)**, replace the **throttle position sensor (TPS)** at the same time.

- **TPS part #:** 23210-30010 (or equivalent for your year).

6. **Lubricate the Pedal Mechanism**

- Apply a **light machine oil or silicone spray** to the **pedal pivot points** to prevent future stiffness.
