FA20 / FA24 Oil Cooler Sandwich Plate Adapter

This configurator allows you to customize an oil cooler adapter solution for the FA20 (also known as Toyota 4U-GSE) and FA24 found on several Subaru and Toyota vehicles.

Improved Racing's filter spacer plate allows our sandwich plates to clear the lip around the recessed filter found on these engines. The spacer also features two 1/8" NPT ports so that sensors can be added if desired.

Step 1

• The ENV-139 is a simple sandwich plate with no oil thermostat. This unit should be used primarily in track-only cars.
• The ENV-131 (-10AN ports) and ENV-132 (-8AN ports) sandwich plates feature an oil thermostat to prevent overcooling of your engine oil on the street and to ensure quick warmup times.
• We recommend using -10AN ports and -10AN oil lines to minimize restriction.
• We recommend choosing the 180°F or 200°F thermostat for street cars, and the 212°F thermostat for track cars that run high viscosity engine oil.

Step 2

• Select the ENV-117 oil filter spacer. This is required for the sandwich plate or filter takeoff to work with the FA20 / FA24 engine's recessed filter flange.

Step 3

• The required filter thread extension bungs are sold separately and are selected in the remaining steps. The FA20 / FA24 engines use a M20x1.5 filter thread, so only this thread size is shown. Two extension bungs are required: one for the sandwich plate, and one for the spacer. These are high quality bung screws machined from hardened 410 stainless steel.
