Autotech's Vent Plate is designed to open up a straight pathway for air that flows through the factory intercooler. In stock form, the fender liner is so close to the backside of the intercooler, that optimum airflow is reduced, forcing the air to find its way out beneath the liner. By freeing up the airflow off the back of the intercooler, better heat exchange takes place, increasing the intercooler's effectiveness at cooling the intake air. Our louvered plate remains effective at preventing debris damage to the intercooler core, while allowing excellent airflow. Made from 6061 aluminum, the Vent Plate comes powdercoated black, complete with laser-etched AUTOTECH logo and mounting screws. Fits all 1.8T Beetle, Golf 4, and Jetta 4, 1999 on.
