Michael. 2313 Report post Posted July 27, 2017 They really don't add much from what I've seen unless running an aftermarket computer and cams adjusted to specs that suit the ITBs. A lot of coin for small gains. But they sound good. I've got the 3UZ in my car, and like most modern v8s has the dual length intake manifold for tuned torque gains in the low to mid range. Makes quite a noticeable difference, originally my vacuum solenoid for the internal butter fly valves was faulty so wasn't working for a few months until I noticed the issue.
