if i want to get my car tuned with a wide band do i need to get another o2 bung on my exhaust? if i do need another one, is there some kind of plug i can use to plug it while it's not in use?

 

its not 100% necessary but its cheap enough and easy to do if you can weld or have a good hookup.

the bung is a M18 x 1.5 nut...plug it with a M18 x 1.5 nut

 

or a m18 x 1.5 bolt if your into mf type stuff, but if you're strictly lesbian go with what xenocron said.

 

I just went to the hardware store and brought my o2 sensor in and just went around and test fitted ---- until I found a nut that fit and then welded that onto my dp. No problems ever and cheaper then a actually bung.

 

thanks for th replys
