The NA Miata, known for its lightweight design and engaging driving experience, has become a beloved choice among car enthusiasts. One area that can significantly enhance the performance of this classic roadster is the ignition system. Upgrading ignition components can lead to better engine efficiency, improved throttle response, and even increased horsepower. In this article, we’ll explore the costs, installation processes, and potential power gains associated with upgrading ignition components on the NA Miata.
Understanding the NA Miata Ignition System
The ignition system in the NA Miata consists of several key components that work together to ignite the air-fuel mixture in the engine cylinders. These components include:
- Ignition Coil
- Distributor
- Spark Plugs
- Spark Plug Wires
Understanding how each of these components functions will help you appreciate the benefits of upgrading them. The stock ignition system is adequate for everyday driving, but as performance demands increase, so does the need for more robust ignition components.
Cost of Upgrading Ignition Components
The cost of upgrading ignition components on the NA Miata can vary widely based on the parts you choose and whether you opt for professional installation or a DIY approach. Here’s a breakdown of potential costs:
- Ignition Coil: $50 – $150
- Distributor: $100 – $300
- Spark Plugs: $10 – $30 each
- Spark Plug Wires: $50 – $100
- Labor Costs: $100 – $300 (if professionally installed)
In total, you might expect to spend anywhere from $300 to $1,000 depending on your choices and whether you do the work yourself.
Installation Process
Installing upgraded ignition components can be a rewarding project for those who enjoy working on their cars. Below is a general guide to the installation process:
Tools Needed
- Socket Set
- Wrench Set
