These Hi-Tech hydraulic lifters from COMP Cams have a greater bleed rate, which greatly increases vacuum and throttle response, and decreases valvetrain noise. They are designed primarily for street machines or racing applications where a vacuum rule is in place, or where you must run a hydraulic cam.
