Volkswagen originally kept the air filter boxed up, preventing dirt and engine gunk from quickly ruining your filter, guiding the air from the D-pillar. Many conversions eliminate this necessary element, and leave the filters exposed to the elements and heat. A clogged air filter sucking hot air can seriously starve your engine of one of the key ingredients required for efficient horsepower.  The Vanaru custom air filter housing utilizes the space behind the rear taillight and isolates the air filter from the harsh environment of the engine bay. This not only keeps it clean and functioning properly, but also allows it to pull cool, fresh air directly from the vents Volkswagen originally provided. When it is time to inspect or replace your air filter, the housing is easily pulled out by removing the two nuts on the retaining plate. The filter used in our application is a common, easily replaceable unit.
