What are some practical modifications I can make to my Nissan Juke?

I recently purchased a Nissan Juke and I am looking to make some modifications to enhance its performance and appearance. Can anyone suggest some practical mods that I can do myself without breaking the bank?

You can start by upgrading your air intake system with a high-flow air filter. This will improve your car's throttle response and engine sound.

Another easy mod you can make is installing a cat-back exhaust system. This will not only improve your car's exhaust note but also increase horsepower and torque.

Changing the spark plugs and replacing them with iridium ones can also boost your Juke's performance by providing a stronger spark for better ignition.
