What are some affordable upgrades for a Nissan Micra?

I recently purchased a used Nissan Micra and am looking for some ideas to improve its overall performance and appearance. What are some affordable upgrades that I can make to my Micra?

One affordable upgrade for a Nissan Micra is to install a cold air intake system. This can improve the engine's power and efficiency.

Upgrading the exhaust system is another cost-effective way to improve the performance of your Micra.

Changing the spark plugs and wires can also make a noticeable difference in the car's performance.
