Which manifold should I install my EGT Probe on my 1999-2007 Super Duty? Left side or Right side?

Here at Glowshift, we recommend installing the probe of the Exhaust Temperature Gauge into the Right (Passenger) side manifold. The reason we suggest this location is because the passenger side manifold is easier to access through the fender well and or from under the truck than the driver side manifold. However, installing the exhaust temperature probe to the Drive side manifold will still provide you an accurate reading of your exhaust temperatures. The install location is at the customer's discretion.
