Narrative:
We experienced moderate wake turbulence from a B737 4 miles in front of us. We were flying the ILS runway 25L with the localizer and GS captured by the autopilot; 8 NM out; when suddenly the aircraft started to shake and the autopilot started compensating strong roll movements. Suspecting wake turbulence I decided to disconnect the autopilot; apply power; and climb to get out of the wake. Once out of the turbulence we reported the incident to lax tower and flew most of the approach one dot above the GS. The turbulence continued through the whole approach phase almost down to the runway. I can tell that because I tried to recapture the GS about 1 NM from the runway and I felt a light roll force as I tried to descend to the GS; so I decided to land beyond the 1500 aiming marks.

Title: Hawker 800 Captain reported encountering wake turbulence four miles in trail of a B737 on approach to LAX.
Narrative: We experienced moderate wake turbulence from a B737 4 miles in front of us. We were flying the ILS Runway 25L with the LOC and GS captured by the autopilot; 8 NM out; when suddenly the aircraft started to shake and the autopilot started compensating strong roll movements. Suspecting wake turbulence I decided to disconnect the autopilot; apply power; and climb to get out of the wake. Once out of the turbulence we reported the incident to LAX Tower and flew most of the approach one dot above the GS. The turbulence continued through the whole approach phase almost down to the runway. I can tell that because I tried to recapture the GS about 1 NM from the runway and I felt a light roll force as I tried to descend to the GS; so I decided to land beyond the 1500 aiming marks.
