Jass Performance Bi-Layer Spark Plug Cover (NA/NB Miata)
Technical Features & Design:
- Unique Bi-Layer Finish: Features a solid black base coupled with a precise brushed stainless steel top accent. This mirrors our signature Roadster design language (perfectly complementing our scuttle panels).
- Functional Air Vents: Engineered air slots are integrated to actively vent heat and prevent overheating of the ignition leads, a common wear issue due to the engine's cooling dynamics.
- Discrete Installation: Uses existing mounting points for a clean, secure, and subtle fit with no visible hardware required.
- Engine-Specific Fitment: Available in separate versions to ensure a perfect bolt pattern match for different engines.
Enthusiast Benefits:
- Extended Lead Life: The functional air vents reduce heat soak on the rear ignition leads, directly addressing a factory weakness and saving you money on premature replacements.
- Instant Aesthetic Upgrade: Replaces the plastic factory cover with a visually striking, polished piece that immediately cleans up the engine bay for a truly finished look.
- Show-Quality Detail: The bi-layer finish and polished stainless steel provide a unique, high-end touch that appeals to enthusiasts focused on detail and quality control.
