I just bought a wideband from jason at the rx7store. Can i use this in place of the old sensor or do I have to install it separately?

 

It's best to install it at the bottom of the downpipe or front of the midpipe/cat section.

 

thanks that helps me out a lot (thumbs up)

 

If you already have the downpipe installed, it's easiest to put in the midpipe....mine is about 2-3" from the dp-mp flange and is nearly vertical. You have to play around with positioning to clear the drivetrain (cable has to clear too!).
