Narrative:

We were 3000 ft and 5 miles outside of jalto on the ILS 27R into phl with the autopilot engaged. We encountered wake turbulence [from] the aircraft in front of us which knocked the autopilot off. Without much deviation at all; the PF recovered the aircraft to straight and level flight. We then notified ATC and [were] offered a slower speed of 160 kts which we accepted. This gave more separation between our aircraft and the aircraft we were following. No further disruption occurred.the wake turbulence was detected by short yet very noticeable bank to the left and then right. Also; the autopilot was kicked off by the event. ATC did not allow enough spacing to prevent wake turbulence encounter. I took over manual control of the aircraft and slowed to aircraft to offer proper separation. Suggest more spacing between aircraft.
