Autotech AST COMPOSITE COLD AIR INTAKE, GOLF4/JETTA4 1.8T

Autotech has addressed both issues with our new Composite Cold Air Intake Kits. The factory airbox is completely removed and a custom K&N air filter with an integrated velocity stack is placed down low in the fender well to ingest cold outside air. Significant horsepower and torque is gained, as is a throaty intake growl when putting the hammer down! Don't settle for competitor's heavier steel units when you can enjoy the ultra lightweight performance that composite provides, at a comparable price! Dyno results show a significant increase in power and torque over stock. Our 337 GTI made a peak increase of 8 hp and 7.5 ft lb of torque, and an increased average of over 14 hp across the entire rev range. Exempt under C.A.R.B. Executive Order D-375-5.
