Ok, guys here is the deal. The stock se-r radiator is 5/8ths thick, the stock nx rad is 15/16ths(1"), and the gtir is also 15/16ths(1"), but the fin count is different and set-up for high speed while the nx is set-up more for stop and go.
This has been talked about many times and there has been guys who have had 3 nx's and all measured 15/16ths(1"), which is the true nx rad size.
