Functional & Performance Testing
Each Bosch Alternator and Starter is tested to ensure functionality and performance aligns with manufacturer specifications. This testing means the part will produce the same performance as the OE part.

Endurance Testing
To ensure Bosch replacement parts deliver optimal performance for the lifetime of the part, test benches simulate the lifetime of the component to prove durability and endurance requirements are met.

Water Intrusion Testing
Bosch water intrusion testing ensures that part function does not vary due to any water impact during inclement weather. Splash water tightness testing to IPX4, IPX4K, and IPX9K standards.

Climate Stability Testing
All new Alternator and Starter product releases are subjected to cold storage (-40F), heat storage (+248F), and changes in humidity to ensure parts work in all temperatures and can withstand thermo-shock.
