The aluminum JRspec connector, with a 22mm diameter and available lengths of 6cm, 10cm, and 16cm, is expertly designed for intake system construction. Its durable aluminum alloy composition, coupled with a special paint finish, provides excellent thermal insulation and protection for the flowing air. The connector's 2mm thick wall ensures it is lightweight yet highly resistant to inlet pressure, and it is also easy to weld. The high-gloss finish not only reduces intake weight but also enhances the aesthetic appeal. Outer Diameter: 28mm.
