Review ACURA 3.5l Throttle Body Oem Miles fits TL 2009–2014

The **Acura TL 3.5L (2011 2013) Throttle Body (Part # 14KKP-H29)** is a precision-engineered component designed to deliver optimal airflow and throttle response for the iconic V6-powered Acura TL models from the 2011 through 2013 generations. This throttle body serves as the critical interface between the engine s intake system and the throttle valve, ensuring smooth acceleration, precise idle control, and reliable performance under varying driving conditions. Crafted from high-quality materials, including durable plastic and reinforced metal components, this throttle body is engineered to withstand the demands of daily driving while maintaining a clean, responsive throttle action. The design incorporates a **drive-by-wire (DBW) system**, allowing for electronic control of throttle position, which enhances fuel efficiency, reduces emissions, and provides a more refined driving experience compared to traditional cable-operated systems. Whether you're restoring a classic TL, upgrading an existing intake system, or addressing performance-related issues, this throttle body is a direct-fit replacement that restores factory specifications, ensuring seamless integration with the **J35A engine** and its associated intake manifold, mass airflow sensor (MAF), and throttle position sensor (TPS). Built to meet Acura s stringent quality standards, this part is ideal for both professional mechanics and DIY enthusiasts seeking a reliable, long-lasting solution for their vehicle s throttle control system. Proper installation, including calibration of the throttle body and ECU relearn procedures, is essential to guarantee optimal performance and prevent potential drivability issues.

Buying a used Acura TL with a 3.5L naturally aspirated V6 engine (specifically models from 2011, 2012, or 2013 with a throttle body, not turbocharged) can be a solid choice if you prioritize reliability, comfort, and driving dynamics. Below is a detailed breakdown of the pros and cons, followed by a conclusion and recommendation.

### **Pros of Buying a 2011 2013 Acura TL 3.5L Throttle Body**

1. **Reliability and Durability**

The 3.5L J35 engine (used in these TL models) is known for its robustness, especially when maintained properly. It is a naturally aspirated V6 with a cast-iron block and aluminum head, which tends to hold up well over high mileage if the oil changes were consistent. Many examples with 150,000 200,000 miles can still run strong with basic upkeep.

2. **Proven Power and Performance**

The 3.5L engine produces 275 280 horsepower and 260 lb-ft of torque, which is more than adequate for daily driving and highway cruising. The throttle body (as opposed to a turbocharged or direct-injection variant) is simpler and less prone to failure compared to more complex fuel systems. The engine responds well to minor tuning (e.g., cold air intake, performance exhaust) for a noticeable power boost without major modifications.

3. **Comfort and Ride Quality**

The TL is a rear-wheel-drive coupe with a well-tuned suspension that balances sportiness with comfort. The interior is spacious for a coupe, with quality materials (especially in higher trims like the Type S) and a quiet cabin. The manual transmission (if available) is smooth and engaging, while the automatic is reliable and predictable.

4. **Resale Value and Brand Prestige**

Acura TLs hold their value better than many domestic or budget-oriented luxury cars. The brand carries a reputation for reliability and performance, which can make these models easier to sell later. The TL s sporty styling and V6 engine also appeal to buyers looking for a premium driving experience without the cost of a German or Japanese luxury brand.

5. **Maintenance Costs (Compared to Competitors)**

While maintenance isn t cheap, the 3.5L engine and Acura s drivetrain are less costly to repair than turbocharged or direct-injection engines (e.g., a 2011 2013 BMW 335i or Audi S4). Common issues like oil leaks or timing chain wear are manageable with budget-friendly fixes. Acura dealerships and independent mechanics are familiar with these models, making repairs more straightforward.

6. **Aftermarket Support**

The TL has a strong aftermarket following, with parts and upgrades readily available. Performance chips (e.g., AEM, Haltech), suspension kits, and exhaust systems are common and can enhance driving dynamics without breaking the bank.

7. **Fuel Efficiency for a V6**

While not a hybrid or diesel, the 3.5L TL gets around 18 22 MPG in the city and 26 30 MPG on the highway, which is respectable for a V6 sedan/coupe. This is better than many turbocharged or supercharged competitors of the era.

8. **Driving Dynamics**

The TL s rear-wheel-drive layout and balanced weight distribution make it more engaging to drive than front-wheel-drive competitors. The Type S variant (available in 2011 2013) adds a sport-tuned suspension, Brembo brakes, and a limited-slip differential, making it a more dynamic choice for enthusiasts.

### **Cons of Buying a 2011 2013 Acura TL 3.5L Throttle Body**

1. **Common Engine Issues**

- **Oil Leaks**: The 3.5L engine is prone to oil leaks from the valve cover gasket, rear main seal, and oil filter housing gasket. These are relatively inexpensive to fix but require attention.

- **Timing Chain Stretch**: Some engines develop timing chain stretch over time, leading to rattling noises and potential valve train issues. This is more common in high-mileage examples but can be diagnosed with a scan tool.

- **Carbon Buildup**: Naturally aspirated engines like this can develop carbon deposits on intake valves over time, reducing performance. This is often fixed with a valve cleaning procedure (e.g., carbon spray or professional cleaning).

- **Water Pump Failure**: The water pump is known to fail around 100,000 150,000 miles, often accompanied by a whining noise. Replacing it is a labor-intensive job but necessary to avoid overheating.

2. **Transmission Problems**

- The 6-speed automatic transmission (used in these models) is generally reliable but can develop slipping or rough shifting over time, especially if fluid changes were neglected. The manual transmission is more durable but requires more maintenance.

- Some owners report issues with the torque converter or solenoid over high mileage.

3. **Electrical Gremlins**

- Acura TLs from this era are notorious for electrical issues, such as faulty sensors (e.g., camshaft position sensor, crankshaft sensor), intermittent power windows, or infotainment glitches. These can be frustrating to diagnose and repair.

- The 2011 2013 models also had early issues with the backup camera system, which could fail or require recalibration.

4. **Rust and Body Issues**

- Depending on the region where the car was driven, rust can be a concern, particularly in the wheel wells, rocker panels, and undercarriage. A thorough inspection of the chassis is essential.

- The TL s coupe body style is more prone to denting and paint issues than a sedan, which can affect resale value.

5. **High Maintenance Costs Over Time**

- While initial maintenance costs are moderate, the cumulative cost of repairs (e.g., water pump, timing chain, suspension) can add up, especially if the car is driven hard or neglected.

- Acura dealership labor rates are often higher than independent shops, which can increase repair costs.

6. **Limited Safety Features**

- Compared to modern standards, these models lack advanced safety features like adaptive cruise control, lane-keeping assist, or top-tier crash-test ratings. The TL s safety is adequate but not cutting-edge.

7. **Depreciation**

- While the TL holds value better than many competitors, it has depreciated significantly since its peak. Buying a used example means you re paying a fraction of its original price, but you ll still need to budget for potential repairs.

8. **Cabin Noise and Wind Noise**

- The TL s coupe body style can be noisy at highway speeds, with noticeable wind noise and cabin rattles. This is more noticeable than in a sedan or hatchback.

9. **Limited Cargo Space**

- As a coupe, the TL s trunk is small and less practical for large items compared to a sedan or SUV. This may not be an issue for daily drivers but could be a drawback for those needing more space.

10. **Discontinued Model**

- The TL was discontinued after 2013, which means parts availability is still good but may decline over time. This could make future repairs slightly more challenging as older parts suppliers phase out.

### **Conclusion**

The 2011 2013 Acura TL with a 3.5L throttle-body engine is a **solid choice for buyers who prioritize reliability, driving enjoyment, and a balance of luxury and performance**. It s a well-built car that can last well over 200,000 miles with proper maintenance, and its V6 engine offers a satisfying driving experience without the complexity of turbocharged or direct-injection systems. The aftermarket support and resale value are also strong points.

However, **buyers should be prepared for potential engine and transmission issues**, particularly oil leaks, timing chain stretch, and electrical quirks. Rust, body condition, and maintenance history are critical factors to investigate before purchasing. If you re comfortable with basic maintenance or have access to a trusted mechanic, this TL can be a rewarding and enjoyable car to own.

### **Recommendation**

- You want a **reliable, fun-to-drive coupe** with a naturally aspirated V6 engine.

- You re okay with **moderate maintenance costs** and can address common issues (oil leaks, water pump, timing chain) proactively.

- You prefer **RWD dynamics** and a **premium interior** without the complexity of a turbocharged or hybrid system.

- You find a **well-maintained example** (under 150,000 miles, with service records) that has passed a **pre-purchase inspection (PPI)**.

- You re not planning to drive it aggressively (hard acceleration, track use) daily, as this can accelerate wear on the engine and transmission.

- You **cannot afford or do not want to handle minor repairs** (e.g., oil leaks, water pump replacement).

- You prioritize **modern safety features** (e.g., backup
