Description
Genuine Bosch New fuel rail for 2011-2016 GM 6.6L LML engines. These are the exact same rails you would get from a GM dealer & include a 1 year unlimited-mileage warranty.
We recommend replacing these to ensure the longest lifespan for your new injectors. Re-using old rails can lead to contamination and damage to your new injectors.
