See how important this little part is!
With no hoover bit, the base of the oil cooler. This allows air to bypass the oil cooler, significantly decreasing the effectiveness and leading to higher oil
temperatures and shorter engine life.
The Awesome Powdercoat hoover bit for SCAT / EMPI fan shrouds completely fills the gap at the base of the oil cooler,
ensuring that all of the air meant for the
oil cooler goes through the oil cooler.
WHAT IS A HOOVER BIT?
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.
