The Vibrant Performance Heat Sink O2 Bung (10419) is precision-machined from T304 stainless steel to provide a strong, corrosion-resistant solution for mounting oxygen sensors while reducing heat exposure to the sensor body.
Featuring an M18 x 1.5 thread pitch, this bung is specifically designed for Bosch LSU 4.9 wideband O2 sensors, offering improved durability and performance in high-temperature environments. The finned exterior design acts as a heat sink, helping to dissipate exhaust heat away from the sensor for improved reliability and extended lifespan.
