AEM Exhaust Back Pressure Sensor Install Kit 302064 User Manual

The 30-2064 Exhaust Back Pressure Kit is designed for use with the 30-2340 4 Channel 
UEGO Wideband controller from AEM Performance Electronics.  When mated to the 
30-2064 EBP kit, the 30-2340 4 Channel UEGO Wideband controller gives accurate 
Air/Fuel ratio readings from UEGO sensors that are mounted pre turbo.   
 
Exhaust gasses can reach very high temperatures and are corrosive.  Sensors mounted 
directly to the exhaust manifold/header will not survive.  The parts included in the EBP 
kit were selected to ensure accurate pressure readings without sacrificing sensor life.  
NOTE: ALL COMPONENTS IN THIS KIT MUST BE USED.

							Page  2 Installation: 
1.  Install the -4 to 1/8” NPT Male adapter into the exhaust manifold/header.  The 
adapter can be threaded into a tapped 1/8” NPT hole or welded.  A common 
location to install the adapter is after the exhaust gases for all cylinders have 
mixed.   
2.  Connect one end of the -4 hard line to the -4 adapter installed in step 1.  The 
hard line can be bent over a generous radius to help with installation or 
clearance.   DO NOT SHORTEN THE HARD LINE. 
3.  Connect one end of the -4 flex line to the remaining end of the -4 hard line 
using the supplied -4 union. 
4.  Connect the pressure sensor to the remaining end of the -4 flex line using the 
-4 male to 1/8” NPT Female adapter.  A small amount of thread sealant can 
be used on the pipe threads. 
5.  Mount the sensor using the supplied sensor clamp and hardware.  The 
sensor should be mounted in a vertical or near vertical position to prevent 
moisture from the exhaust gasses from collecting in the sensor. 
6.  Connect the 3 pin connector on the 4 Channel UEGO Wideband controller 
harness to the mate on the pressure sensor. 
7.  Double check all fittings to make 100% sure there are no exhaust leaks.  
Any exhaust leaks in the hard line, flex line, or fittings will kill the sensor 
almost immediately.
