It's a perfect fit!
Being AC Delco it's a perfect fit. It functions well as it's capable of moving a lot more air through your motor. I'm certainly happy with it, as the price was very reasonable. Especially compared to the aftermarket alternatives.Being an original equipment part I'm sure it's durable enough to stand the test of time. I look forward to many years of service.

GENUINE GM INTAKE
Best intake for a turbo ls build. 1600+ HP through it so far. Seen 40 PSI a few times.

Good intake for low to high rpm power
Good quality intake for ls swap for a cheaper price than used. Especially if you are going to use aftermarket rails and injectors

This is 2010 and up and requires a MAP sensor with the hole on one side. Other than that it’s pretty dang nice.
