3.3 How to fabricate a copper heat sink

Use a 4” x 4” (10cm x 10 cm) sheet of copper sheet metal 14ga (1.5mm) thick. Drill a hole in the

center with the same diameter of the oxygen sensor threads ~3/4” (19mm).

Fold the sides up 45 deg and mount it between the sensor and the bung like you would a big

washer. Orient it such that the sides are exposed to good airflow.
