Narrative:
Level at 3000 feet; 190 knots; flaps 5. Minimum speed approximately 160 knots (aircraft weight about 250K). Direct budee to join runway 09 localizer. Co-altitude and 4-5 miles behind a aircraft Y (on TCAS). Flew through their wake turbulence. We initially rolled right 10 degrees; then rolled quickly left to 25-30 degrees left bank. Never got a bank angle aural warning. First officer disconnected the autopilot and we simultaneously received a momentary (less than 1 second) stick shaker. No other cautions or warnings or alerts. Received clearance for and executed the visual approach to 09. Landed with no issues. Made an aml entry. Flew through preceding plane's jet wash. More spacing but tough to judge in light winds.
