This features 360 degrees of oil containment using seven Cosworth style rubber trap doors. This dramatically slows down oil sloshing on acceleration, deceleration and cornering.
  The momentum of oil forces the trap doors closed sealing oil close to the sump pick-up and helping to prevent cavitation and starvation. 

NOTE: This will not fit the Saab 9000 oil pan/sump  

  The upper plate features better forward and rearward sealing to the sump to prevent oil rising up the walls of the sump under heavy acceleration and deceleration.  
  The upper plate also features five Cosworth style trap doors allowing for faster oil return to the center of the of the baffle chamber. The trap doors in the upper plate allow oil in while preventing oil from escaping.
