What is Secondary Air Injection?

The Secondary Air Injection system is part of your Land Rover’s emissions control setup. During cold starts, the system injects fresh air into the exhaust stream to help reduce harmful emissions by promoting faster catalytic converter operation. It’s a common system in early 2000s Discovery II models and is required for vehicles built with federal or California emissions packages.

If your vehicle has SAI, this is the correct harness to maintain full engine and emissions functionality.
