The exhaust system is designed to optimize the engine's exhaust flow, reducing backpressure and increasing exhaust velocity. This results in improved engine efficiency, as well as a more powerful and distinctive exhaust note.

The kit also includes a fuel pump module, which is designed to deliver more fuel to the engine, ensuring that it receives the necessary fuel for optimal performance. This component works in conjunction with the engine's fuel system to provide a consistent and efficient fuel supply.

Lastly, the Mopar 68303090AA engine kit includes all necessary mounting hardware and installation instructions. The installation process is designed to be straightforward, allowing you to easily upgrade your Wrangler's engine performance with minimal hassle.

In summary, the Mopar 68303090AA engine kit is an excellent choice for Dodge Wrangler owners with a 6.4L 392 Hemi engine who are looking to maximize the potential of their engine. With its high-performance intake system, high-flow air filter, high-performance exhaust system, and fuel pump module, this kit delivers increased horsepower, torque, and engine efficiency, resulting in a more powerful and satisfying driving experience.
