The SwirlRepair BMW 6-Cylinder Inlet Manifold is a remanufactured and upgraded version of the original manifold. The swirl flaps on the original manifold are unfortunately not designed strongly enough, so sometimes they can break. When breaking, parts of the swirl flaps can fall into the combustion chamber, thus causing fatal damage to the entire engine.
There are so-called blanking kits on the market. With these kits the swirl flaps are simply removed and the remaining openings in the manifold are covered with blanking plates. This obviously prevents the risk of breaking swirl flaps, but the swirl flaps have not been installed without reason. Without swirl flaps the fuel consumption is noticeably higher at part load, i.e. in the area engines are used most of the time, so there is a cost factor incurred in using blanking plates. In addition, engines produce more smoke and emissions at part load with swirl flaps removed. So installing a blanking kit makes the vehicle illegal for road use.
With the SwirlRepair manifold we offer an alternative. It is not just remanufactured with original parts, but its weak parts are upgraded. The swirl flaps are much more robust and machined from aluminium, and they come with steel shafts that have a bigger diameter. Other components such as levers and shaft seals are also upgraded. In addition, the manifold comes ready to install with a new set of gaskets.
The purchasing procedure includes a part exchange, so we send a shipping label with the order, and with this the old part can be sent back once the new part has been installed. We don’t charge this additionally unless the old part should not be returned.
