### **Pros and Cons of Buying Harley-Davidson Part Number 31964-07A (11-17 FLSTC Heritage Softail Classic Ignition Coil Cables, Trsh)**

#### **Pros:**

1. **OEM Quality and Compatibility** This is an original Harley-Davidson part designed specifically for the **2011-2017 FLSTC Heritage Softail Classic**, ensuring a perfect fit and reliable performance. Aftermarket parts may not match the exact specifications, potentially leading to compatibility issues or reduced longevity.

2. **Reliability and Durability** Harley-Davidson parts are built to withstand the demands of heavy-duty motorcycle use. The ignition coil cables in this set are designed to handle the electrical demands of the engine, reducing the risk of failure over time.

3. **Easy Installation** Since these are genuine parts, they should integrate seamlessly with the existing wiring and ignition system. The **Trsh (Trim Set)** designation indicates they are part of a complete ignition system upgrade, which can simplify installation compared to sourcing individual components separately.

4. **Warranty Coverage** Purchasing from an authorized Harley-Davidson dealer or an approved seller often includes warranty protection, providing peace of mind in case of defects or premature failure.

5. **Maintenance of Resale Value** Using OEM parts helps maintain the bike s original condition, which can be beneficial if you plan to sell the motorcycle in the future. Buyers often prefer bikes that have been maintained with genuine components.

6. **Consistency with Factory Specifications** The ignition system plays a critical role in engine performance. Using Harley s recommended parts ensures that the bike operates as intended by the manufacturer, avoiding potential tuning or performance issues that might arise from non-OEM components.

#### **Cons:**

1. **Higher Cost** Genuine Harley-Davidson parts are significantly more expensive than aftermarket alternatives. The price reflects the brand s reputation, quality, and the cost of sourcing and manufacturing these components. For budget-conscious buyers, this can be a major drawback.

2. **Limited Availability** Depending on the seller, genuine Harley parts may not always be in stock, leading to potential delays in receiving the order. Aftermarket parts are often more readily available from multiple suppliers.

3. **Potential Overkill for Minor Issues** If the ignition coil cables are failing due to a minor issue (e.g., wear from age or minor electrical corrosion), replacing them with a full OEM set may be more expensive than necessary. In some cases, a partial replacement or repair might suffice.

4. **Depreciation Factor** Harley-Davidson parts, like the motorcycle itself, depreciate over time. If you re not planning to keep the bike long-term, the upfront cost of OEM parts may not be fully justified by the bike s resale value.

5. **Dependence on Authorized Dealers** To ensure authenticity and warranty coverage, you may need to purchase from an authorized Harley-Davidson dealer, which could limit your options compared to buying aftermarket parts from online marketplaces or specialty shops.

6. **Potential for Unnecessary Upgrades** If the bike is otherwise in good condition, upgrading the ignition system solely for cosmetic or perceived performance benefits may not be justified. Harley-Davidson s ignition systems are generally robust, and failures are often due to age rather than inherent design flaws.

### **Conclusion:**

The **Harley-Davidson 31964-07A ignition coil cables (11-17 FLSTC Heritage Softail Classic, Trsh)** are a high-quality, reliable choice for maintaining or upgrading your motorcycle s ignition system. They offer the advantage of **OEM compatibility, durability, and warranty support**, which are ideal if you prioritize long-term reliability and the bike s original condition. However, the **higher cost and limited availability** make them less appealing for budget-conscious buyers or those who prefer aftermarket alternatives.

If your primary concern is **performance, longevity, and maintaining the bike s value**, then investing in these genuine parts is a strong recommendation. On the other hand, if you re looking to **save money or address a specific issue without a full system upgrade**, aftermarket options or partial replacements might be more practical.

### **Recommendation:** - **Buy the OEM part if:**

- You want to ensure the highest level of compatibility and reliability.

- You re performing a full ignition system refresh or restoring the bike to factory specifications.

- You value warranty coverage and plan to keep the motorcycle long-term.

- You re willing to pay the premium for genuine Harley-Davidson quality.

- **Consider aftermarket alternatives if:**

- You re on a tight budget and the cables are failing due to age rather than a systemic issue.

- You re comfortable with sourcing parts from trusted aftermarket brands (e.g., **Screamin Eagle, Dyno Don s, or other reputable suppliers**).

- You re only addressing a specific problem (e.g., replacing just the coils or wires) rather than upgrading the entire system.

For most riders, the **OEM part is the safest choice**, especially if the bike is a cherished or high-value motorcycle. However, weigh the cost against your priorities performance, budget, or convenience to make the best decision for your situation.
