Why are performance upgrades often sold as "kits"?

Performance upgrades are typically sold as "kits" to simplify the installation process for enthusiasts and mechanics alike. When components are bundled together in a kit, it reduces the complexity involved in selecting compatible parts, making it easier for consumers to choose what they need for their upgrades. A kit usually includes everything required for a specific performance upgrade, such as installation instructions, which helps ensure that all parts work together seamlessly. This convenience encourages more users to attempt installations themselves or complete the process quickly and efficiently if they seek professional help.

While safety standards and compliance are critical aspects of automotive upgrades, they do not directly relate to why products are packaged as kits. The other options, such as influencing purchase timing and improving engine cooling, may apply in different contexts but do not directly address the primary motivation behind the kit packaging strategy. The focus on simplifying the installation process is a key reason kits are popular among those looking to enhance their vehicle's performance.
