Upgrading your 1995 M3 3.0 to a 1996-on M3 3.2 engine is a popular performance option, but can be a complex task. Lot of little things can be overlooked – like the heater hose that runs under the intake manifold to the engine front cover. The ‘95 M3 engine front cover uses a flange with rings to receive the heater hose. The ’96-on engine doesn’t have a corresponding flange, instead expecting a heater pipe to be present – connecting up to the front cover with an a o-ring seal. Our simple, efficient solution: a CPF that lets you retain your ’95 heater hose, clamps and hardware. Problem solved in minutes, with no need for upgraded pipes or seals.
