Q:Will this fit my 2011 Qx56 Infitity ?
Quin W.
A:BEST ANSWERHi Quin, I'm pleased to assist you. This will not work. This is only for GM LS2/3/7 engines. Nissan manufactures Infinity. We checked, and we do not currently have the direct-fit ECM compatible with the 2011 Infiniti QX56 Base 8 Cyl 5.6L in stock. If you need any other parts for your vehicle, please visit our website via the link provided below. I hope this was useful.
