MADE IN U.S.A.

M18mm x 1.5mm thread - fits all O2 sensors in American, Japanese, European, cars, trucks, motorcycles - everything!

• fits narrow and wideband sensors (works with innovate ,AEM,Zeitronix,FJO ..... ALL sensors)
• STEPPED/shaped to fit against exhaust tubing with No grinding needed on exhaust tubing, With our bungs just drill a 7/8" hole with a step drill and weld the bung on.  Save labor $ AND get a better fit!
• Mild steel  (for easiest welding)  MIG or TIG weld,it can even be brazed. Many people use these bungs with all types of steel tubing with no problem because the bung is much thicker than the tubing. Normal mild steel welding rod/filler/wire can be used to weld these to stainless.    
• CORRECTLY DIMENSIONED -thick enough so it won't warp when welding, CORRECT LENGTH so that the sensor is in the exhaust stream but not too far, so it does not obstruct flow, this is important as most of our customers are tuners and want max performance. Beware some other bungs or nuts are to thin, they will warp and leak or ruin the threads and they are a big pain to weld to round exhaust pipe.
