Product Description

The Injen Technology X-1128-BB SuperNano-Web dry air filter is a high-performance, reusable intake filter designed to deliver increased airflow while maintaining superior engine protection. Its proprietary dry filtration media captures fine particles efficiently without requiring oil, helping protect sensitive MAF and MAP sensors and reducing maintenance compared to traditional oiled filters.

Built in a tapered conical shape with deep pleats for expanded surface area, this filter supports improved throttle response and power gains when paired with cold air or short ram intake systems. The 4-inch clamp-on flange makes it ideal for many Injen intake kits and custom setups. Simply clean and reuse for long-term performance and reliability.
