HF-Series Charge Pipe Kit For BMW 335i E90 E91 E92 / 135i E82 E88 N55 Only. This Charge Pipe is a popular performance product in all types of motorsport. The series part consists of a plastic tube with a small wall thickness. Under influence of time, temperature and pressure, the material is very brittle and cracked. This results in broken connections or busted pressure lines. Not only annoying because of the defect, but rather a major threat to the turbocharger and engine. The HF-Series Charge Pipe is an aluminum pipe with CNC turned flanges without constrictions. It is optimized flow and manufactured in 76mm diameter. The air throughput is maximized and improves the flow. So a perfect basis for maximum performance is created in earlier response and increased durability. Aluminum pressure pipe – CNC machined flanges – Perfect fit – Plug’n’Play – Pressure and temperature resistant. Without taper for maximum airflow – Flow-optimized for early response.
