The Injen X-1134-BR is a high-performance, conical 8-layer oiled cotton gauze air filter engineered for maximum airflow and superior engine protection. Designed as a direct fit for many Injen intake systems and select Evolution intake systems, this filter features a Twist Lock base for secure, hassle-free installation. Built and assembled in Pomona, California, USA, the X-1134-BR reflects Injen Technology's decades of filtration engineering expertise rooted in both racing and street performance.
