Out of ignorance on my part, why do they offer a range? 3/8 intake 27 to 33. I was checking the intake bolts, something you are supposed to do now and then, and the 3/8 tightened about 20 degrees when set at 30. At 27 it probably would not have moved. Some people don't believe in torque wrenches, on the other hand, I check everything. Have a set of wrenches ranging from the sublime to the ridiculous.
