TBSS intake vs 2011 5.3 intake for NBS

Im wanting to do the intake swap on my 2003 silverado. I found a deal on a complete 2011 silverado intake with rail,injectors,TB and bolts but i want to be sure it will fit. the part number is 12638038 on the intake im looking to buy. does anyone happen to know if it will also swap?

They are basically the same. I have read that the 2011 intake has a bigger hole for the map sensor so you will need to do something so it fits. I have a 2008 on my 04 5.3 and my map sensor worked perfect.
