Spark Plug & Plug Wire are same for Aveo 1.4LT & 1.6LT?

Hi,
I am new to cars and this forum. I've bought a used Aveo 2007 make last year. The seller told me that the car is 1.6LT variant. Accordingly, my service center guy changed Spark Plugs & Plug wires recently as it was due. But today I figured out that the car is 1.4LT variant.
Since the change of Spark Plug & Plug Wire, millage has gone down drastically. Is there any compatibility issue with Plug & Wires for the above said variants?

What is your GM part number for your spark plugs/wires? if it is different than the ones we have over here you might have the wrong parts... send us an engine bay pic?

I do not have GM part nos, as the car was not serviced @ GM's Service Center rather it was serviced @ the SC of the seller. Assuming the Seller's SC has fixed Spark Plugs and Plug Wires compatible with 1.6LT variant, will there be any compatibility issues considering the car is actually 1.4LT variant?

Does it run ok? You could check the gap on the spark plug. I wouldn't worry if the car runs well.
