Narrative:
On dogleg to an ILS runway 22L ewr; we experienced an uncommanded roll to the right that increased in rate and approached 30 degrees. We were following another narrow body aircraft and the winds were relatively light at altitude. Spacing was normal 4 to 4.5 miles. I was the flying pilot. We had just received a turn to the right from ATC. While the first officer was responding to the vector on the radio; then aircraft started to bank due to the wake. I disconnected the autopilot immediately; counter rolled to the left; [I] added power and climbed to get out of the wake. We gained about 300 to 400 ft. And rolled farther right than ATC requested. The stall warning activated for about 1 second and the airspeed dropped slightly below our flaps 5 speed with the flaps at 5. Once out of the effect of the wake we rolled back to the proper heading and got back to the proper airspeed and altitude. The first officer immediately informed ATC of the deviation due to the wake turbulence. We intercepted ILS final and had a normal stabilized landing.
