Questions on going from 18" OEM to 20" OEM

[jungy4]

I am not a fan of my current 18" OEM's and want to upgrade to 20" OEM's on my 2011 FX35 for better looks and handling.

Will my center caps and TPMS sensors on the 18's fit the 20's? I am looking for a used set of OEM 20's. What is the easiest way to tell whether the wheels are OEM or aftermarket? I thought the OEM ones have "Enkei" letters on the wheels and I have seen some with and some without. I even went on autotrader to look for FX35 listings and by looking at the pictures of the wheels on there I see that some do have the letters and some don't. Is this something that Infiniti changed sometime?

Any help is appreciated.

The word Enkei may not be printed in front (the viewing face of the rim). If it's truly a OEM rim, the words Enkei and Nissan/Infiniti will be printed at the back of the rim.
I borrowed these images from eBay for a 2011 Infiniti FX35 OEM 20" Rim.



For my 2013, the FX came with 20", and I bought a set of 18" for my winter setup. The 18" rims use the same the center caps and TPMS sensors.

TPMS sensors don't need programmed when you swap?
