Injen Air Intake Kit

Why Injen Stands Apart in the Air Intake Kit Category

When enthusiasts talk about air intake kits, few brands carry the engineering credentials that Injen Technology does. Injen holds the distinction of designing and producing the world's first tuned air intake system, and backs that claim with four patents on the tuning process of an intake system — a milestone no other manufacturer can match. That foundation of innovation is baked into every kit they produce, from their classic SP Series to the more modern Evolution lineup.

The SP Series: Injen's Flagship Aluminum Cold Air Intake

The SP Series represents Injen's benchmark in traditional aluminum cold air intake systems. These kits incorporate several of the brand's patented technologies, including MegaRam (MR) Technology (Patents 7,359,795 and 7,669,571) and Air Fusion (Patents 7,757,548 and 7,721,699), which work together to optimize airflow and maintain a safe air/fuel (A/F) ratio across the entire power band — all without requiring aftermarket tuning. Each SP kit ships with Injen's fully serviceable SuperNano-Web dry air filter, engineered to increase filter surface area for greater airflow and superior filtration. SP kits are also available in multiple finishes, letting drivers add a personalized touch under the hood.

The Evolution Series: Next-Generation Sealed Intake Systems

For those seeking a more enclosed, sealed system, the Evolution Series steps up with a one-piece roto-molded housing built from cross-linked high-density polyethylene for extreme durability. The housing utilizes Injen's proprietary Twist-Lock System to securely attach the SuperNano-Web filter — eliminating unnecessary hardware and simplifying installation to just minutes with no cutting or drilling required on nearly all fitments. Evolution systems also feature a forward-facing ram air scoop that channels cool, fresh air directly to the engine. Like the SP Series, Evolution intakes are tuned and tested on Injen's in-house dyno to replicate stock fueling while delivering real horsepower and torque gains.

Shared Qualities Across the Injen Air Intake Lineup

• No aftermarket tune required — kits are designed to maintain safe factory fuel mapping right out of the box.
• SuperNano-Web filtration — some Evolution filters feature pleats measuring over 1.25" deep for maximum air volume and filtration efficiency.
• Dyno-proven performance — every system is validated on Injen's in-house dyno, not just claimed on paper.
• Premium hardware throughout — stainless steel band clamps with inner protective liners, reinforced automotive-grade silicone couplers, and quality fasteners ensure a secure, leak-free fit.
• Limited Lifetime Warranty — Injen stands behind every intake system and air filter with a limited lifetime warranty to the original purchaser.

Choosing the Right Injen Air Intake Kit

Whether you prioritize the classic look and feel of a polished aluminum tube (SP Series) or the sealed, cold-air efficiency of a roto-molded housing (Evolution Series), Injen offers a vehicle-specific solution engineered from the ground up for your exact application. Each kit is designed in a 3D workspace for a precise, drop-in fit — no guesswork, no modifications. Explore the full Injen Air Intake Kit selection to find the right system for your build.
