First, we only recommend direct fit parts. You may have changed the engine's air/fuel ratio by changing the intake.

Check if the cooling system has been bled of air and ensure the cooling fans are working.

Changing the air intake does not but replacing the radiator and not bleeding the system would.

Kjlow2008, can't the cold air intake have an affect on the MAF? He has a new radiator and t-stat and it ran fine. The problem started after the CAI was installed. At least that is what I understand.

The Civic uses a MAP sensor and no MAF.

It could be running correctly initially but then there could be coolant leakagesomewhere resulting in the temperature increase.
