OIL SUMP, THIN LINE The thin line oil sump extends only 2 inches below your engine case. The front of the thin line sump features a ram air profile to force air between the engine case and sump for even greater cooling. The increased oil capacity helps prevent oil starvation and pump cavatation during hard cornering and acceleration. Can be used in conjunction with a Maxi pump (part-no.: 010 0710 / 010 0711) to provide total oil cooling and protection for your engine. Comes with all assembly parts.
