I have an external oil cooler kit for all inline-four VW engines, uses a
'sandwich' adaptor to connect the hoses just above the oil filter. Hoses are
about 42 inches long, braided type with Earl's aircraft-style fittings, 3" x
10" x 2" cooling area, quality cooler made by Setrab of Sweden. Great
condition, barely used. $75 plus shipping.
