Fit perfectly and solved my fuel adjustment problem.

I have the same code on banks 1 and 2 Fuel trim system is bad, banks 1 and 2 (PO171B and PO174B). In other words, an intake leak in both banks. I've tried using a smoke machine, starting liquid and gas to find the leak but none of that worked. Replaced intake gaskets and problem solved.

Pros
