The ATS 2029302272 Aurora 3000 Turbocharger is a quick spooling turbo charger that is great for all around performance on your 03-07 Dodge 5.9L Cummins. The 58mm inducer on the turbo is a very nimble and highly responsive unit. Safe for stock engines and stock components, towing and daily driving become much easier due to the turbo doing more work, instead of relying on the engine with a restrictive factory turbo. The increase air volume will utilize all fuel injected into the cylinder creating a more complete and efficient combustion event. This will result in lower EGTs, better throttle response, and a more efficient/useable torque curve.
