Smaller Throttle Body Beneficial at lower RPMs?
Hello folks, I've got a 1996 Jeep Grand Cherokee with the 4.0l I6 engine. I've been considering replacing my throttle body with one from a Jeep 2.5l I4. They are externally identical, including linkage, but the 2.5l TB has a much smaller bore.
Anyone have experience with this? The Jeep runs at about 1800RPMs on the highway, so I'm not worried about lack of power with the smaller TB. Am I likely to notice any positive change at all before the smaller TB runs out of air at really high RPMs?
