Narrative:

I was a pilot flying on the right seat. We got a clearance 'maintain 170 kt to dooin; maintain 3000 feet until established; cleared for ILS 4R approach.' the airplane was configured flaps 9 and I kept 170 knots on the approach to runway 4R kewr at 3000 ft before grity intersection. And all of sudden; one object was detected at the right next to us on our TCAS radar about 300 feet below us and within a second it shouted 'traffic; traffic' and 'climb; climb; climb.' I disconnected the autopilot right then and simultaneously brought a pitch up with increased thrust on the steady course of ILS 4R approach. And the pilot monitoring called tower that we had a TCAS climb and traffic below us around 2700 feet. When I reached 3300 feet; TCAS warning was disappeared. There was no more traffic on our TCAS radar. I was still able to stabilize the approach. We were on the ILS 4R approach course with no deflection of HSI and GS on 2 dots above. And the pilot monitoring let the tower know that we were still able to continue the approach. Then I continued the ILS 4R approach and landed on runway 4R kewr. We finished the flight at the gate. Before we got a TCAS warning and RA climb instruction; we didn't have any traffic within 6 miles except an airplane ahead of us on the approach course for runway 4R. We didn't get any traffic report from tower. It was at 3000 feet right before intermediate fix on the ILS approach as the critical phase of flight. Even if it was VFR condition; it was dusk of the day and tower already gave us ILS approach clearance. Although a pilot flying and a pilot monitoring tried to remain vigilant at all times; it was really hard to catch the small traffic without radar surveillance of the tower control; especially on the final course of the approach.

Narrative: I was a pilot flying on the right seat. We got a clearance 'maintain 170 kt to DOOIN; maintain 3000 feet until established; cleared for ILS 4R approach.' The airplane was configured flaps 9 and I kept 170 knots on the approach to runway 4R KEWR at 3000 ft before GRITY intersection. And all of sudden; one object was detected at the right next to us on our TCAS radar about 300 feet below us and within a second it shouted 'traffic; traffic' and 'climb; climb; climb.'

Before we got a TCAS warning and RA climb instruction; we didn't have any traffic within 6 miles except an airplane ahead of us on the approach course for RWY 4R. We didn't get any traffic report from tower. It was at 3000 feet right before intermediate fix on the ILS approach as the critical phase of flight. Even if it was VFR condition; it was dusk of the day and tower already gave us ILS approach clearance.
