When getting a downpipe it asks if you want the O2 bung for wideband. do you need to have this or in what situations would you want this? what are some pros and cons of having or not having this included?

 

I believe a wideband tells you your air/fuel ratio. It's necessary if you have boost. other than that you shouldn't need it.

 

You only need this if you have aw ideband gauge...

 

thanks that what i was looking for. someone i was talking to said it would be necessary if i plan on modding at all, especially upgrading my injectors but i never read anywhere that it was necessary.

so its basically there if i want put in this gauge so i can watch myAFR correct?

 

Yes... exactly.

 

might as well get the extra bung on there, close it off until you're ready to buy the gauge. Less work in the future because you won't have to add a new bung.

 

well it's never neccessary, but if you plan on doing some modifications it is helpful.....

 

Excellent, thats exactly what i wanted to know. thanks for your time guys!
