3. O2 sensor bungs (if used) can be positioned on the header collector where the sensor wires can be routed away from hot

engine components (O2 sensor wire extensions are provided). Drill 3/4” hole and weld bung to collector.

As the exhaust flow passes by
the tube, it creates a low
pressure area on the backside,
which translate into vacuum.
