Injen Technology - Performance Intake Systems, Exhaust Systems, & More

Founded in 1991 by Ron Delgado in California, Injen Technology revolutionized the performance air-intake market with the first tuned intake system, combining innovative patented processes like MegaRam and Air Fusion to improve airflow, engine management, and power—without triggering check-engine lights. Operating from a modern U.S. facility in Montclair, CA, Injen engineers cold-air and short‑ram intakes, mandrel‑bent stainless exhausts, intercoolers, throttle controllers, and reusable SuperNano‑Web filters—each dyno-tested and built to OEM standards.

With four intake-related patents and a legacy spanning over 25 years, Injen’s products offer aggressive tone, solid horsepower gains, and confident fitment. Their exhaust systems feature mandrel‑bent 304‑stainless tubing, TIG welding, and lifetime warranties, designed and hand-crafted in Pomona, CA. Backed by in-house R&D, dyno, laser measuring, and global distribution, Injen continues to empower enthusiasts and racers worldwide with high-quality, performance-driven solutions—proving that true innovation is born in the U.S.A.
