Overview: The Short Ram SP Series is a traditional, underhood air intake system that takes the place of your factory airbox and air filter, and the factory air intake tube. A synthetic dry filter media is used.
Analysis: The Injen SP Series intake system scored well from 3,500 RPM until redline. The OE mounting points are used to to secure the air box. Overall, a good fit but rubber mounts or grommets would be a nice addition.
