civiceg500

I'm building a down pipe for my 95 civic dx and i'm going to incorporate a o2 bung. I wanted to know what size would i need to buy. I found a company that sells o2 bungs and thay come in a variety of sizes. If i were to measure my o2 sensor, do i measure the with of the threads or measure the whole width of the sensor. Unless does anyone know the size for a 92-95 civic o2 sensor.

Standard bung I believe is

18mm x 1.50mm Pitch

Its the same size as a spark plug thread.

I had one welded in on my 95 civic delsol.

It is the same as a spark plug, but isn't that 14x 1.5

M-200/M-250/M-300 Plug and Play Installation Instructions

*Please read the instructions completely through at least once before proceeding with the installation to minimize
errors.
1) Select a location to mount the M-200/M-250/M-300 Plug and Play Controller
Choose a location where the device does not obstruct driver’s view and/or ability to safely control the vehicle. Avoid
locations exposed to direct sunlight and high temperatures. Never mount the device in the engine bay. Excessive heat will
cause failure and damage to the unit.
2) Install the wideband oxygen sensor
Mount the wideband oxygen sensor before the catalytic converter and at least 24 inches downstream from your engine
block or turbo for optimal performance. The sensor element will fail if it is exposed to exhaust gas temperatures above 850
deg Celsius. If you plan to replace your stock narrowband oxygen sensor with the PLX wideband, please read PLXApp004
online for more information. The sensor will directly screw into an 18mm X 1.5mm pitch sensor bung.

I know its 18mmX1.5mm on a '88 teggy LS, the stock one fucked the threads, I bought the only large metric tap the hardware store had (18mmX1.5mm) and magically, it was the right part. I wonder where it went...
