Extruded 6063-T6 body
Fully machined features
Proprietary 6063-T6 FAS thermal CORE

heat transfer
• Retains stock hardware and placement
* Friction Stir Welding is a patented technology only available through a licensed supplier.
Comparison
FAS Oil to Air
• 160 sq in Al. to Air area
• 440 sq in Oil to Al. area
Stock VW Oil to Water
• 40 sq in Alum. to Air area
• 112 sq in Oil to Al. area
Advantages
• Reduced thermal load on the engine coolant
system
• 4 times the amount of contact surface area for
both oil and air over stock
• Eliminates the possibility of intermixing coolant
and ATF as with previous design
• Easier installation with the removal of cooling
lines
Thermal Analysis
• Thermal loading
shown under natural
convection
• *Thermal bench
testing has shown
the cooler to
operate between
175-188F without
air flow.
Testing
* Testing was conducted at 74F with a completely rebuilt transmission
