Quick wideband question:

dragon831 · Oct 18, 2009, 06:07 PM

I plan on getting an aem wideband and just wanted to make sure that my testpipe should have an extra bung, or i'd just have to drill a hole and weld up the sensor in it. Also if i get a testpipe with an extra bung, will the bung being open until i get the sensor in affect anything?

if i were you I would plug the bung until you get the sensor in, I believe when you buy bungs for sensors they come with like a bolt so you can "cap" it off so the exhaust gases don't run out there, I placed my wideband sensor in the downpipe so that when smog season came I can just switch out the test pipe for a cat and wouldn't have to worry bout moving the sensor

yea whoever you buy your test pipe from just tell them that you want the extra 02 bung with a cap they'll know what it is. That way its capped off until you get your wideband.

O2 sensor thread is 18mmx1.5 so you can use a number of O2 bung capping devices including but not limited to old spark plug, transmission oil plug bolt, short 18mm bolt or old O2 sensor.

Have them put a bung on the passenger side of the test pipe. I just put in my AEM wideband, and it was a clean, and simple install because the factory 02 sensor wire grommet is under the passenger side of the car, covered by a heat shield. You can install the AEM 02 sensor on the passenger side and tuck the harness clip in that heat shield and run the rest of the wiring under the carpet, through the dash to your desired mounting location.
