03 04 Cobra Eaton Supercharger Swap Kit – eaton swap kit
The 03 04 Cobra 4.6L DOHC Eaton Supercharger Swap Kit is a popular aftermarket kit that provides a significant power increase to the Mustang Cobra’s engine. Here are some details about this kit:
- The kit includes a complete Eaton supercharger assembly, a cast aluminum intake manifold, intercooler, fuel system upgrades, and all necessary hardware and gaskets.
- The Eaton supercharger is a positive displacement unit that compresses the incoming air and delivers it to the engine at a higher pressure. This results in a significant power increase, with typical gains of 100-150 horsepower over the stock engine.
- The cast aluminum intake manifold is designed to work with the supercharger and features larger ports and runners for improved airflow.
- The intercooler is a heat exchanger that cools the compressed air before it enters the engine. This helps to prevent detonation and provides a denser charge for more power.
- The fuel system upgrades include larger fuel injectors, a higher flow fuel pump, and upgraded fuel lines and rails. This ensures that the engine has sufficient fuel to support the increased power output.
- The kit is designed to be a bolt-on installation and can be completed with basic hand tools. However, some tuning may be required to optimize the performance of the engine with the supercharger installed.
- Overall, the 03 04 Mustang Cobra 4.6L DOHC Eaton Supercharger Swap Kit is a popular and effective way to add significant power to the Mustang Cobra’s already impressive performance.
