GReddy Airinx and GReddy Air Intake Systems are designed to provide a easy and simple solution for helping increase air intake flow to your vehicle’s engine. When super high-flow is important, for specific turbo applications, a free flowing dual-ply, 3 dimensional urethane foam element with inner funnel adapter may be recommended. While for more everyday use, an application specific or universal GReddy Air Intake System with 4-layer synthetic, deep pleated, air intake filter system will be the ideal choice. All GReddy air intake systems feature a dry filter element to protect sensitive O.E. intake sensors. more details on - https://www.carid.com/greddy/airinx-suction-short-ram-air-intake-system-mpn-12020907.html
