Default 2008-2014 wrx to sti intake manifold conversion

Hey guys, I have a 2013 wrx with the plastic intake manifold. I have the 2011 sti intake manifold, sti stock map sensor, and 2011 sti throttle body waiting to be installed. I was wonder if all I need to do is swap out the old intake manifold for the new one, extended the wrx map harness, and plug it in to the sti throttle body map sensor. I have ported the sti intake manifold so it would be an upgrade. I'm having an issue trying to figure out weather the map sensor plug from the wrx engine harness, is capable of being plugged into the sti manifold. All help is greatly appreciated. Thanks

Plastic doesn't radiate heat the way metal does. How is this swap an upgrade? Because it's ported a little bit? You will see zero positive gains from this.

Yes but again, zero gains man. The map sensor probably won't work right and now your cutting wires. Good luck getting that to last long term. You are better off keeping the WRX manifold.
