OK I just did an experiment and here is what I came up with. Check out this website:

Measurement A = 90
Measurement E = 5.5
Measurement L = 17.5
Measurement D = 25
The result holding my torque wrench at 90 degrees came out to 25 ft lbs which was the same torque as a normal torque wrench setting without an extension. If you hold the torque wrench at 0 degrees then you would need to set the torque wrench to 19ft lbs. The eddy air gap intake calls for 25 ft lbs so no adjustment was required as long as you held it 90 degrees. Hope this helps explain.
