For the BMW 335 Diesel E90/91/92/93 series vehicles
This hose was designed to overcome the known boost and oil leakage of the original fitment hose. Though this normally goes undetected due to its location, eventually total failure occurs.
Our solution is a 4ply Fluorosilicone hose to withstand the temperatures and pressures involved, but more importantly resist the degradation from oil. This is combined with CNC machined alloy couplers for the perfect, no leakage, fitment.
