This exhaust bung is a must have for folks running an engine that requires an O2 sensor. The standard O2 position on most Porsche's is on the drivers side (Left hand drive cars) in the 10:00 position. For some high-end engine builds, two O2 sensors may be needed as these motors need to read O2 from both header banks. Please specify O2 sensor position requirements when ordering. Pricing is for one O2 bung and the installation on ERH header collector.
