Vehicle Repairs. We've Got What It Takes. In the electronics and sensor technology sector, febi offers a growing range of replacement parts of OE matching quality which are suitable for numerous vehicle types. Our range consists of high-quality parts, including air flow / mass meters. The measurement of air has become one of the most important tasks the engine management system has to process. This component signal is used to calculate the injected fuel quantity and for regulating the exhaust gas recirculation. Like many sensors, this component has evolved with the development of technology to meet demands placed upon it. Quality by Conviction. All air mass and air flow meters supplied by febi are intensively tested by our quality management team. The quality control of electronic components is carried out with the aid of a high-resolution X-ray device which is used to check the integrity of the circuitry. Precisely Fitting Production. Anyone who repairs their own car knows the problem: inexpensive replacement parts from the independent parts trade can deviate from the mould and can be difficult to install at the intended location. febi makes all the difference: all replacement parts are manufactured precisely and it goes without saying that production tolerances are adhered to. This is the only way to guarantee an optimal fit.
