<VV> O2 sensors

[Daniel Monasterio]

Hi Frank,

   Just returning from my FLAPS with a pair of Bosch 15729, 4 wire, sensors. They said it is wide band but, don't know how to check this as I couldn't get that info on the net. 

   I plan to install them vertically (downwards) but, just after checking it is the right one.

Daniel,
    Make sure they are WIDE BAND and not the narrow band ones as used in most of the current production autos.  And make sure you mount them so they are pointed DOWNWARD by at least 15 degrees from the horizontal (steeper is even better).
     Let us know how they work out.

I am almost ready to reinstall my 64 GB powertrain  but, plan to instal O2 
sensors on the dual (w/crossover) exhausts previously  and,...  have some 
concerns about: 

1.- How close to the  exhaust manifolds they should be placed ? 

2.- How much deep they will  go into the pipe ? 

3.- A recomended brand and model  ? 

Thanks a lot

If you are buying a wide-band kit, they will usually come with the  sensor. 
If you want two sensors, just buy another one at that time. Most screw   
into the factory-sized weld-in Bung. (Available from Summit Racing and   
others.) Just install the bungs and a plug for each until you are ready. to  go. 
The closer to the manifold the better,  but don't let the sensor  intrude too 
much into the air stream coming out of the manifold.
