Easily read installation instructions. Unfortunately, they don't tell you that you might need to remove the coolant hose from the throttle body, so be prepared to do so. Took about 30-40 minutes. I noticed some midrange torque gains (above 2,000 RPM) and hear it whistle only when really accelerating. Haven't had it long enough for MPG reports. This is my second Poweraid TBS and will purchase again for future vehicles.
