Wrinkle finned spark plug head bolt covers, also known as Harley-Davidson part number 63422, are accessory parts designed to enhance the aesthetic appeal of Harley-Davidson Twin Cam engines produced between 1999 and 2017. These covers do not directly affect engine performance but are popular among Harley-Davidson enthusiasts for their unique appearance. Let's discuss the pros and cons of buying these covers to help you make an informed decision.

Pros:

1. Improved visual appeal: Wrinkle finned spark plug head bolt covers add a distinctive and visually appealing look to your Harley-Davidson engine. They are often considered a desirable upgrade for Harley-Davidson enthusiasts.

2. Protection against the elements: These covers help protect the spark plug head bolt threads from debris, moisture, and other contaminants, potentially extending the life of the bolts and improving overall engine maintenance.

3. Customization: Wrinkle finned spark plug head bolt covers are available in various finishes, including chrome, black, and polished aluminum. This allows you to customize the look of your engine to suit your personal style.

Cons:

1. Cost: Wrinkle finned spark plug head bolt covers are not cheap. They can be a significant investment, especially when compared to functional engine upgrades.

2. Installation complexity: The installation process for these covers can be more complicated than installing standard parts. Harley-Davidson recommends having them installed by a professional mechanic to ensure proper fitment and torque specification.

3. Non-functional upgrade: These covers do not offer any performance benefits to the engine. They are purely for aesthetic purposes.

Conclusion:

Wrinkle finned spark plug head bolt covers, part number 63422, are a desirable yet non-functional engine upgrade for Harley-Davidson Twin Cam 99-17 models. These covers offer improved visual appeal, protection against the elements, and customization options. However, they come with a higher cost, installation complexity, and do not provide any performance benefits. Ultimately, the decision to purchase these covers depends on your personal preferences, budget, and priorities as a Harley-Davidson enthusiast. If you value the unique look and potential longevity benefits, these covers may be worth the investment. If you prefer functional engine upgrades or are budget-conscious, you may want to consider other options.
