Even if the Injen IS Series Short Ram is a classical "underhood" intake system, don't think it possesses less performance than other Injen intakes. The IS Series is a creation of the same meticulous product development and testing as all other Injen's products. It's manufactured of the same quality components, and features the exact the same high flow EA Nanofiber dry air filter. The air intake tube is crafted from the 6061-T6 aluminum alloy for durability and light weight. Only top quality silicone connectors are used for all connections, which provides strength, flexibility while maintaining, and thermal stability. Made of stainless steel, hose clamps guarantee a solid seal that won't deteriorate and loosen. All these parts are united in a superior quality air intake system, which will improve your vehicle's performance and look great under the hood.
The IS system installs in place of your factory airbox and air intake tube. It's carefully engineered, with CNC machined brackets and adapters, to ensure an exact fit. Installation is fast and simple and can be completed under the hood. There's no need to get underneath the car or do any significant component relocating. Everything necessary for installation is supplied, including comprehensive instructions. The IS Series Air Intake System is backed by a Limited Lifetime Warranty.
