Review BMW Secondary Air Injection Pump Suction Hose 7557907 Oem fits E90 E92 E82 2006–2013

The **BMW 11727557907 Secondary Air Injection Pump Suction Hose (OEM Part Number 7557907)** is a precision-engineered component designed exclusively for BMW s E90, E92, and E82 vehicle platforms, spanning the model years 2006 through 2013. This hose serves as a critical link in the secondary air injection system, which plays a vital role in reducing harmful emissions by supplying additional air into the exhaust manifold during the post-cranking phase of engine startup. Crafted from high-quality, durable rubber with reinforced internal braiding, this hose is engineered to withstand the demanding conditions of BMW s high-performance engines, including exposure to elevated temperatures, engine vacuum, and potential oil or coolant contamination. Its seamless construction ensures a secure, leak-free connection between the air injection pump and the intake manifold or air filter housing, maintaining optimal airflow and system efficiency. The hose s precise fitment is tailored to BMW s exacting standards, guaranteeing compatibility with the E90 3-Series, E92 3-Series Coupe, and E82 Z3 roadster, where it interfaces seamlessly with the secondary air injection pump assembly. Whether replacing a worn or cracked original hose or upgrading an aftermarket system, this OEM-specification part ensures reliable operation, compliance with emissions regulations, and long-term durability, making it an indispensable component for maintaining the integrity of BMW s secondary air injection system.

### **Pros and Cons of buying a BMW E90/E92/E82 Secondary Air Injection Pump Suction Hose (Part Number 11727557907, 2006 2013 Models)**

1. **Direct OEM Fitment** This is a genuine BMW part, ensuring compatibility with the E90, E92, and E82 platforms (3-Series, Z3, and Z4) from 2006 to 2013. It will install without modifications, reducing the risk of improper fitment issues.

2. **Reliability** BMW s secondary air injection system is designed to reduce emissions by injecting air into the exhaust during cold starts. A failing suction hose can lead to check engine lights, poor idle, or increased emissions. Replacing it with an OEM part ensures proper function and longevity.

3. **Prevents Further Damage** A worn or cracked suction hose can cause air leaks, leading to incorrect air-fuel ratios, potential damage to the catalytic converter, or even failure of the air injection pump itself. Replacing it early prevents more costly repairs down the line.

4. **Ease of Installation** The hose is relatively straightforward to replace, requiring only basic tools. Most mechanics or even experienced DIYers can complete the job in under an hour, especially if the car is already lifted or in a bay.

5. **Aftermarket Alternatives May Be Risky** While aftermarket hoses exist, they may not match the OEM s durability or sealing quality. An OEM part minimizes the risk of leaks or premature failure.

6. **Supports Original Equipment Standards** If you prioritize maintaining the car s original specifications (e.g., for resale value, performance tuning, or emissions compliance), an OEM part is the safest choice.

---

1. **Cost** OEM BMW parts are significantly more expensive than aftermarket alternatives. The price for this specific hose can range from **$50 $100 **, depending on the seller and region. This may be a deterrent for budget-conscious buyers.

2. **Limited Availability** While not rare, OEM BMW parts can be harder to find than generic automotive hoses. You may need to order from a BMW specialty dealer, an online marketplace, or a used parts lot, which could introduce delays.

3. **Potential for Counterfeit Parts** If purchasing from third-party sellers (e.g., eBay, Amazon, or random online shops), there is a risk of receiving a **counterfeit or refurbished part** that doesn t meet OEM standards. Always verify the seller s reputation and part authenticity.

4. **Overkill for Minor Issues** If the suction hose is only slightly cracked or leaking, some owners opt for a **cheaper aftermarket hose** as a temporary fix. However, this is not recommended for long-term reliability, as aftermarket parts may fail sooner.

5. **Labor Costs if Professional Installation is Needed** While the part itself is easy to replace, if you re not comfortable working under the car, a mechanic may charge **$50 $150 in labor**, adding to the total cost.

6. **Environmental and Emissions Concerns** If the air injection system fails entirely (due to a bad hose or pump), the car may not pass emissions tests in regions with strict regulations. Replacing the hose ensures compliance.

### **Conclusion**

Buying the **BMW 11727557907 secondary air injection pump suction hose** (OEM) is the **best long-term solution** for maintaining your E90/E92/E82 s emissions system, preventing further damage, and ensuring reliability. While the upfront cost is higher than aftermarket options, the **durability, fitment, and peace of mind** justify the investment especially if you plan to keep the car for years or prioritize original equipment standards.

If budget is a concern, **verify the part s authenticity** before purchasing, and consider checking for **used OEM parts** (often sold at a discount) from reputable sources like **RockAuto, BMW Parts Zone, or local junkyards**. However, **avoid cheap aftermarket hoses** unless you re certain they meet BMW s specifications, as they may fail prematurely and lead to recurring issues.

- **Buy OEM (11727557907) from a trusted source** (e.g., BMW dealership, authorized online retailers, or verified used parts sellers).

- **Replace it as soon as symptoms appear** (check engine light, rough idle, or visible cracks) to avoid secondary damage.

- **Pair with a new air injection pump** if the system is failing (some pumps fail alongside the hose).

- **Document the repair** if selling the car later, as it demonstrates proper maintenance.

For most owners, **the cost of the OEM part is outweighed by the benefits of reliability and avoiding future problems.** If you re on a tight budget, **prioritize the hose over the pump** (as the pump is more expensive), but replace both if the system is degraded.
