Review BMW Throttle Body Itb Left Right Side fits M3 E90 E92 E93 S65 2008–2013

The **BMW 337.bm1h11 Throttle Body (Intake Throttle Body, ITB) for the E90, E92, and E93 M3 (2008 2013)** is a precision-engineered component designed to regulate airflow into the engine s intake system, directly influencing throttle response, power delivery, and overall performance. This high-performance throttle body is specifically tailored for the **S65 6.0L V12 engine**, which powers the M3 in its most aggressive and track-focused iterations, including the **M3 CSL, M3 Competition, and M3 E93 models**. Crafted from durable materials, including high-grade aluminum and reinforced plastic components, the ITB is built to withstand the extreme demands of high-performance driving, whether on the street, track, or in competitive racing environments. The design features a **dual-chamber intake system** with precise throttle blades that open and close smoothly, ensuring optimal airflow efficiency while minimizing turbulence and backpressure. This throttle body is compatible with both **left-hand and right-hand drive configurations**, making it a versatile upgrade for M3 enthusiasts looking to enhance throttle response, reduce lag, and improve engine breathing. Whether installed as part of a full intake upgrade or paired with a high-flow air filter and intercooler system, this ITB delivers a noticeable improvement in engine performance, making it an essential component for those seeking to maximize the potential of their S65-powered M3. Built to exacting BMW specifications, it ensures a seamless fit with the existing intake manifold and wiring harness, while its robust construction guarantees longevity even under the most demanding conditions.

### **Pros and Cons of Buying a 2008 2013 BMW 337i (E90/E92/E93) with S65 Throttle Body (ITB Left/Right)**

#### **Pros**

1. **Performance Potential**

- The S65 engine (N63 in later models) is a high-revving, twin-turbocharged inline-six that delivers strong power (300 315 hp in stock form) and is capable of significant upgrades. With the correct throttle body (ITB) and supporting mods, it can push well into the 400 500 hp range.

- The E90/E92/E93 platform is well-suited for engine swaps and tuning, making it a favorite among enthusiasts.

2. **Reliability (Compared to Other BMWs of the Era)**

- The S65/N63 is generally more robust than the N54 (used in 335i models) in terms of turbocharger longevity and oil control issues, though it still requires proper maintenance.

- The E90/E92 chassis is durable, especially with proper suspension upgrades, and the M3 (E92) is particularly well-built for its class.

3. **Aftermarket Support**

- A vast array of performance parts (turbo upgrades, ECU tuning, suspension, brakes) are available, making it easy to customize.

- The ITB (Individual Throttle Body) setup allows for precise throttle response, which is crucial for high-performance builds.

4. **Driving Experience**

- The M3 (E92) is a track-focused car with a stiff chassis, precise steering, and a well-tuned suspension (in stock form).

- The E90/E93 337i offers a more comfortable yet still engaging drive, making it versatile for daily use and performance.

5. **Resale Value (For Well-Maintained Examples)**

- While not as high as newer BMWs, a well-documented, modified 337i with a S65 engine can still hold value among enthusiasts, especially if it s a project car.

6. **Modularity**

- The E90/E92/E93 platforms share many parts, allowing for flexibility in body styles (coupe, sedan, convertible) while keeping maintenance costs consistent.

---

#### **Cons**

1. **Maintenance Costs**

- BMWs, especially high-performance variants, require frequent and expensive maintenance (timing belt, oil changes, turbo inspections, etc.).

- The S65/N63 is known for oil consumption issues if not properly maintained, which can lead to costly repairs if neglected.

2. **Common Issues**

- **Turbocharger Failures:** The S65/N63 turbos (especially early models) are prone to failure if not properly supported with upgraded intercoolers, oil systems, and tuning.

- **Oil Leaks:** The valve cover gasket and oil filter housing gasket are notorious for leaking, requiring frequent checks.

- **Transmission Problems:** The Getrag ZF 6HP21 automatic (common in M3s) can be finicky and may require rebuilds if abused.

- **Electrical Gremlins:** BMWs of this era suffer from wiring issues, sensor failures, and infotainment glitches.

3. **Fuel Economy & Running Costs**

- The S65/N63 is thirsty, especially after tuning. Expect **10 15 MPG** in a heavily modified version, compared to **20 25 MPG** in stock form.

- High-performance tires, upgraded brakes, and suspension components add to ongoing costs.

4. **Project Car Status**

- Fresh turbos (or at least rebuilt ones)

- Upgraded intercoolers and oil systems

- ECU tuning (MHD, Haltech, or custom maps)

- Suspension and brake upgrades

- Possible transmission work (if it s a manual, clutch issues may arise)

- This means **significant upfront investment** before the car is truly drivable.

5. **Depreciation**

- BMWs (especially high-performance models) depreciate quickly. A 2008 2013 337i will likely never regain its original value unless it s a rare or highly modified example.

6. **Inspection Challenges**

- Without a **detailed service history**, it s hard to verify the condition of the engine, turbos, and transmission.

- Some sellers may hide issues (e.g., carbon buildup, rod bearing wear, or failed injectors) until after purchase.

---

### **Ending Conclusion**

- Enjoy **building and modifying** high-performance engines.

- Have **budget and mechanical skills** to handle maintenance and upgrades.

- Prefer a **track-capable or street-legal performance machine** over a plug-and-play solution.

However, it is **not a simple "buy and drive"** purchase. The car will likely require **thousands of dollars in modifications** before it s truly reliable or fun to drive. If you re looking for a **ready-to-go** performance BMW, consider a **pre-built M3 (E92) or a 335i with a well-supported N54 engine swap**.

For the right buyer someone who **loves tinkering, has mechanical experience, and understands the long-term costs** this is an **excellent opportunity** to build a **serious performance car**. For casual buyers or those seeking a **low-maintenance** vehicle, it s **not the best choice**.

---

### **Recommendation**

- A **clean engine bay** (no obvious leaks, fresh turbos, or signs of oil starvation).

- A **well-documented service history** (especially for timing belt, oil changes, and turbo work).

- A **manual transmission** (if you prefer driving) or a **rebuilt automatic** (if you need one).

- Fresh turbos (Garrett GTX or BorgWarner)

- Upgraded oil system (catch can, oil cooler, high-flow filter)

- ECU tuning (MHD or Haltech for reliability)

- Suspension (Eibach Pro-Kit or Bilstein B16)

- Brakes (Brembo or EBC redstuff pads)

- Consider a **pre-built M3 (E92) with a well-supported engine** (N55 or S55).

- Look for a **335i with a N54 engine swap** (if you want a more reliable turbo setup).

- Avoid **high-mileage examples** unless they have **full service records**.

- Rent or lease a **performance BMW** first to experience what you re getting into.

- Start with a **less demanding project** (e.g., a 330i with an N54 swap) before tackling an S65.

This is a **great car for the right person** someone who **enjoys the process of building** and isn t afraid of **high maintenance costs**. If you re not prepared for that, there are **better alternatives** for a more hassle-free experience.
