Special high-flow sandwich plate with 1/2 BSP ports and 2 1/2 inch O-ring diameter. This part is commonly used on FF2000 / Sports 2000 (Ford 2.0L engines). The thickness of the plate is 1 inch so be sure to check for filter clearance.
Note: 1/2 BSP is so close to 1/2 NPT that some experienced mechanics will use a 1/2 NPT fitting in a 1/2 BSP port with the help of some PTFE tape. We recommend using our BSP adapters for maximum reliability.
