New Replacement Cast Iron Exhaust Manifold With Gaskets Nuts Studs Bolts For Diesel Engines

Some vehicles affected: 3 series E46: 330d, 330xd, 330cd. 5 series E39: 525d, 530d. E60: 525d, 530d. E61: 525d, 530d. 7 series E38: 730d. E65: 730d. X3 E83 3.0d. X5 E53 3.0d. Associated part numbers: 11627788422, 11622248166. Please check your VIN on RealOEM.com for compatibility. Smoke coming from under the bonnet, soot evident under the bonnet, smell of fumes – particularly when sat at idle. MOT failure for fume leak. Hissing sounds? Leaking manifold can cause further faults such as engine noise, slower turbo response, less torque, decreased fuel economy. To be sure of the fault it is worthwhile inspecting the exhaust manifold, using a mirror / torch it should be possible to inspect the manifold at which point cracks can usually be seen or soot / fumes can be seen. It is very common for the stainless steel exhaust manifold to crack causing exhaust gases to leak. The stainless-steel exhaust manifolds fitted to many BMW vehicles frequently fail. These manifolds are not suited to the conditions of the fitment and through expansion and contraction with heating /cooling eventually fail. Developing cracks or slits in the manifold causing exhaust gas leaks and the symptoms noted. Install our improved design manifold for a fraction of the price of the OEM part which would just fail again. Our manifold is superior in design to the BMW part, cast from tough Ductile Iron our manifold is the perfect material for the environment in which it is fitted and is suited to the wide temperature range and expansion / contraction. Cast from solid iron with no welds or thin walls to fail.
