AD Auto Parts Fuel Injectors Editorial Review

This OEM Fuel Injection Assembly includes the Fuel Rail Harness, Injectors with Pressure Sensor. Customers have asked if it fits their specific models of vehicles, with mixed results. The product does not fit a 2016 Yukon XL Denali with a 6.2L V8 and it doesn't come with fuel injectors, which must be purchased separately. This product was a good fit for a 2014 Silverado, but a customer had difficulty with finding a fit for their 6.2L engine. Another customer had a 2019 Escalade 6.2, and while the parts were there, they didn't work with their vehicle. The right side part number is also unclear. Overall, the customer experience and reception of this product are mixed and unclear. It appears that the product may work for some specific vehicles and not others.
