Wideband o2 Bung and Cap

[wtf lol]

umm.. i don't know what that is? i was reading another thread about installing a new DP and so i went to CP-E.com and started looking at them and their price but then i came across a "wideband o2 bung and cap". im not too sure what those are. can somebody inform me? please

 

[terbow]

a bung is a lil threaded cylendar that you weld into your exhaust pipe so you can add the wideband sensor. since widebands come with their own sensor u cant just replace yours or the car will freak out. and the cap is just a bolt that fits in the bung so if u dont have the sensor in there u dont ahve a leak.

thanks!
