Therefore you cannot return them or cancel your order during production and receive your prepayment back. In case of faulty assembly or manufacturing defects, the part will be replaced. We cannot tell you exactly our production time, as part of the work is carried out by third parties. You cannot return the part if you cannot install it or if you realise you have made a wrong choice. Only in case of a defect on our part (prior to installation of the part), we will make a replacement or refund your money. During operation, we do not accept any complaints, as we cannot verify that our parts have been installed correctly. We do not provide a guarantee for the engine.
