The Injen SP Series Intake Systems Feature the Patent Pending MR Technology Process for Optimal Gains and a Safe A/F Ratio. The Injen SP Series Intake System does not limit itself to just a Cold Air System or Short Ram System. The MR Technology process has its effects on both types. The Injen SP Series Intake is The World's First Tuned Intake System. This intake also features Injen's own oil-less SuperNano-Web air filter, which is washable and reusable. The use of a non-oiled filter guarantees no harm to your vehicle's MAF (mass air flow) sensor and provides free air flow, while also filtering out more particulates than traditional oiled cotton-gauze air filters.
