Powder Coating
Engine Cooling

The offset oil cooler sealing frame, A.K.A "Hoover Bit".  This is the #1 most forgotten
part on a VW engine rebuild!
Not including this part leaves a huge gap that allows air to
flow AROUND the oil cooler instead of THROUGH the oil cooler.
 I have been told this
part is named after Bob Hoover, a long time VW enthusiast that spread the word about
the importance of this little part. Don't forget this part! Your engine will thank you.
