GrimmSpeed has released their air intake system for the 11-14 Subaru WRX that utilizes a Hybrid Cold Air/Short Ram intake design. Based on GrimmSpeed's testing and research, design requirements for this intake became simple. The MAF sensor must be protected from the heat of the engine bay for more accurate readings while the filter must not be close enough to the ground such that water/hydrolocking are a concern. Grimmspeed has determined the MAF sensor must be placed relative to the filter and air straightener, similar to the OEM airboxfor consistant and reliable airflow readings. They have designed the intake tube to be no longer than necessary with minimum bend angle for a reduction in airflow restriction. The heat shield provides a seal between the induction area and the hot engine bay to keep air intake temperatures low. The GrimmSpeed intake for the 11-14 WRX achieves each of these requirements and more, what they have accomplished is a true hybrid of traditional Cold Air Intakes and Short Ram Intakes, with all the advantages and none of the compromises.
