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 loading shown under natural convection

Thermal Analysis

Testing• *Thermal bench testing has shown the cooler to operate between 175-188F without air flow.

* Testing was conducted at 74F with a completely rebuilt transmission running fully synthetic ATF at full load in 3rd gear for 40 min.
