Stainless Steel Oxygen Sensor Plug

• 304 grade stainless steel oxygen sensor plugs
• M18 x 1.5 pitch thread, standard Oxygen sensor thread size.
• When building your exhaust system it makes good sense to use stainless steel for these fittings to prevent corrosion and ensure you will be able to remove the plug come time for tuning.
• Male Thread

Note: A well-designed exhaust system will have a port for the oxygen sensor and another port in an easily accessible position plugged off for use when the car is being dynoed.
