Autotech has long stated that open air filters in the engine compartment are
a poor substitute for a good K&N® filter in the factory airbox. The primary
reason is because any gains seen by removing the restrictive airbox are quickly
lost when the motor ingests the hot air from the engine compartment. While the
K&N panel replacement filters are still a good solution, the best solution
for maximum power is now here: The Autotech Cold Air Intake.
The factory airbox has been found to be restrictive, robbing precious
horsepower and stifling the engine's intake note under acceleration.
The intake tube mates to the mass airflow sensor via a silicone hose coupling
for high performance that you demand and the race look you desire. Autotech
engineers also insisted on using only original connectors to retain the factory
air pump hose for an OEM quality installation2. Easily the best Cold
Air Intake available today for your Golf or Jetta. Available for Mk4 2.0L, 1.8T,
and VR6 models.
