Injen Engine Short Ram Air Intake

Injen SP Series Short Ram Air Intakes: Patented Performance Engineering

When it comes to unlocking more power from your engine without a full cold air setup, Injen Technology stands in a class of its own among engine short ram air intake manufacturers. Founded in 1998 and built on decades of precision metalworking expertise inherited from its sister company RD Metal Works, Injen has spent over 25 years perfecting the science of air intake design — and their short ram lineup is a direct result of that relentless engineering focus.

What Sets Injen Short Ram Intakes Apart

The foundation of Injen's short ram advantage lies in intellectual property that no competitor can replicate. Injen Technology is the world's first tuned air intake manufacturer, holding four patents specifically on the tuning process of an air intake system — a distinction unique in the aftermarket industry. Their SP Series short ram intakes incorporate several of these breakthroughs, including:

• MegaRam (MR) Technology (Patents 7,359,795 and 7,669,571) — a patented venturi stepping process that allows engineers to "tune" the intake for maximum power by precisely adjusting airspeed at the MAF sensor during the design phase, eliminating check-engine lights while optimizing output across the entire RPM range.
• Air Fusion Technology (Patent 7,721,669) — further refines airflow characteristics within the intake pipe for smoother, more consistent delivery to the throttle body.
• SuperNano-Web Dry Air Filter — manufactured in-house at Injen's California facility, this fully serviceable filter provides increased surface area for greater airflow and superior filtration, and can be cleaned and reused rather than replaced.

The SP Series: Injen's Flagship Aluminum Intake Line

Injen's SP Series represents the flagship line within their traditional aluminum intake systems. Available in multiple finishes — including polished, wrinkle black, and standard black — these short ram kits are vehicle-specific, engineered for a precise, direct-fit installation without guesswork. Each system is designed so that a safe air-fuel (A/F) ratio is maintained throughout the power band, meaning real-world drivability isn't sacrificed for peak dyno numbers.

Beyond performance, the SP Series delivers a distinctly aggressive induction sound that enthusiasts appreciate as part of the driving experience. Injen's in-house air filter manufacturing line gives their engineering team the freedom to develop custom filter shapes optimized for each specific intake design — a level of integration that off-the-shelf filter solutions simply cannot match.

Built to Last: Lifetime Warranty Confidence

Every Injen SP Series short ram intake ships with a limited lifetime warranty covering defects in materials and workmanship — a testament to the confidence Injen places in their manufacturing standards. Nearly three decades of experience and several thousand product applications have made Injen a household name among enthusiasts who demand dyno-proven solutions for their vehicles.

Whether you drive a sport compact, a performance sedan, or a sport coupe and want the benefits of a short ram setup — quicker throttle response, improved induction tone, and a clean engine bay presentation — Injen's SP Series short ram intakes represent one of the most technically sophisticated options in the category.
