TOM's Racing - Engine Filter for 2010-2015 Prius / CT200h

The Super Ram II Air Cleaner was designed to trap airborne dust and debris with minimal air intake resistance. The filter portion of the cleaner features a new triple layered foam material made up of cell structures. This enables trapping more unwanted debris before it reaches the engine than ever before, with the smallest air intake resistance. -

Tom's scrutinized over even the finest dust particles and the materials to make up the filter so maximum power figures can be achieved. They then succeeded in removing the pressure loss commonly seen on polyurethane foam to make up the most efficient unit.

Tom's discovered that the pressure drop is caused by the cellular film present in the filter. A special process removes these unwanted particles.
