Review EPARTS Breather Bolts Aluminum Fit Harley And Carb Cam Cvo fits SOFTAIL TWIN DYNA TOURING EFI

The **eParts 996812306389 Breather Bolts** are a precision-engineered set of high-performance components specifically designed for Harley-Davidson s **Softail Touring, EFI-equipped Twin Cam 114, CVO, and Dyna models** featuring carbureted or fuel-injected engines. These breather bolts serve as critical airflow regulators, ensuring optimal engine breathing by controlling the flow of air through the crankcase ventilation system while minimizing oil loss and maintaining peak performance. Crafted from durable, corrosion-resistant materials, these bolts are engineered to withstand the high temperatures and pressures inherent in high-performance applications, providing a secure and leak-proof seal that prevents oil vapor from escaping while allowing proper crankcase ventilation. Ideal for riders seeking enhanced engine efficiency, reduced oil consumption, and improved throttle response, these breather bolts are a straightforward yet impactful upgrade that aligns with Harley-Davidson s commitment to both performance and longevity. Whether you're preparing your bike for a long-distance tour, a track session, or routine maintenance, these bolts offer a simple yet effective solution to keep your engine running smoothly while adhering to the strict specifications of your model s engine bay. Their compatibility with Harley s advanced Twin Cam and CVO architectures ensures a seamless fit, making them an essential component for any serious rider looking to optimize their bike s performance without compromising reliability.

### **Pros and Cons of Buying Eparts 996812306389 Breather Bolts for Harley-Davidson Softail Touring (EFI, Carb, Twin Cam, CVO, Dyna)**

1. **OEM Quality and Fit** These breather bolts are designed as direct replacements for Harley-Davidson s original components, ensuring proper sealing and airflow. They are manufactured to meet Harley s engineering standards, reducing the risk of leaks or performance issues.

2. **Compatibility with Multiple Models** The part number (996812306389) is listed for several Harley-Davidson models, including the **Softail Touring (EFI and carbureted), Twin Cam, CVO, and Dyna**. This makes them a versatile choice if you re unsure about exact model-specific variations.

3. **Prevents Oil Leaks and Contamination** The breather system vents crankcase fumes to the atmosphere while preventing oil from leaking into the air intake. Worn or damaged breather bolts can allow oil to enter the intake, fouling the carburetor (if equipped) or EFI sensors, leading to poor performance or damage. Replacing them ensures proper ventilation and prevents contamination.

4. **Easy Installation** These bolts are straightforward to replace, typically requiring only a socket wrench and a new gasket (if applicable). No major disassembly is usually needed, making them a quick and cost-effective maintenance task.

5. **Cost-Effective Maintenance** Compared to more complex engine repairs (such as carburetor cleaning or EFI sensor replacement), breather bolts are inexpensive. Replacing them proactively can avoid more expensive issues down the road.

6. **Improves Engine Reliability** A properly functioning breather system reduces internal engine pressure buildup, which can strain seals and gaskets over time. Keeping these components in good condition contributes to long-term engine health.

7. **Available from a Trusted Supplier** Eparts is a well-known aftermarket parts distributor with a reputation for quality and authenticity. Purchasing from them reduces the risk of counterfeit or low-quality knockoffs.

---

1. **Potential for Counterfeit Parts** While Eparts is a legitimate supplier, there is always a risk of receiving counterfeit or mismatched parts, especially if ordering from third-party sellers. Always verify the authenticity of the part number and supplier before purchasing.

2. **May Not Fit All Years/Variations Exactly** While the part number covers multiple models, some Harley-Davidson variants (particularly newer CVO or high-performance Dyna engines) may have slight differences in breather system design. Double-check compatibility with your specific year and engine configuration.

3. **Gasket Replacement Required** Depending on the condition of the old breather system, you may need to replace the gasket or seals around the breather housing. If these are worn, they could cause leaks even with new bolts.

4. **Limited Longevity** Like all mechanical components, these bolts can wear out over time, especially if the engine is high-mileage or subjected to extreme conditions. They may need replacement every few years or as part of routine maintenance.

5. **No Performance Benefit** These bolts are primarily for maintenance and preventing leaks; they do not improve horsepower or throttle response. If you re looking for performance upgrades, this part alone won t provide them.

6. **Installation Mistakes Possible** If not installed correctly (e.g., overtightening, cross-threading, or forgetting a gasket), they could cause leaks or damage. Always follow the manufacturer s torque specifications.

The **Eparts 996812306389 breather bolts** are a practical and necessary part for maintaining your Harley-Davidson s engine health, particularly if you re dealing with oil leaks, carburetor fouling, or EFI issues. They offer **OEM-quality replacement**, **versatile compatibility**, and **easy installation**, making them a sound choice for routine maintenance. However, buyers should **verify compatibility with their exact model**, ensure they re purchasing genuine parts, and account for potential gasket replacements.

If your breather system is leaking oil or you ve noticed reduced engine performance due to contaminated air intake, replacing these bolts is a **low-risk, high-reward** maintenance task. For most riders, the benefits far outweigh the minor drawbacks, especially when compared to the potential costs of neglecting this component.

- **Buy from Eparts directly** (or an authorized dealer) to confirm authenticity and avoid counterfeit parts.
