Besides giving you more horsepower, most aftermarket cold air intakes come with a reusable filter that can be cleaned once it gets dirty. These reusable filters also tend to be less restrictive than their stock counterparts and allow for more airflow, increasing the amount of horsepower gained even more. However, if you're not sure how to clean the filter, an air filter cleaning kit is a good investment that will ensure your filter lasts as long as possible.

Your Mustang's sound is almost as important as its performance, and the addition of a cold air intake can improve that as well. Due to the larger diameter piping, your intake will make a louder, more aggressive sound when you put your foot down. Of course, for a really great sound, you may also want to upgrade your exhaust.

When updating your intake, It's usually a good idea to also upgrade your Mustang's exhaust. By upgrading your exhaust, you can ensure that your ride can inhale and exhale with ease.

While a cold air intake that's properly installed can be great for your engine, some require a new tune in order to work correctly. Tuners are also great for future modifications as well as having some improvements of their own.
