MOFOCO 040 SUPER STREET CYLINDER HEADS
MOFOCO boasts the only completely MADE IN USA VW Aircooled Cylinder Heads. The 040 Super Street head is a performance replacement cylinder head with 37.5mm intake valves and 32mm exhaust valves. These heads have been ported and polished for better flow and more low end torque. We have specifically designed these castings for better cooling and better performance than original castings.
