MassAirFlow sensors (MAFs)

The Mass Air Flow (MAF) sensors used in electronic engine management systems can be defective or malfunctioning by time. Karreman Engineering is able to read out the engine control unit and check if your MAF is defective. If your MAF is defective we offer genuine replacements for Bosch and Siemens MAFs for a reduced price.

The MAFs we sell are not a copy or imitations but genuine. We have experienced only trouble with copies and imitation MAFs. From large fuel trim deviations on petrol engines to smoking diesel engines. We (Karreman Engineering) have tested and inspected the MAFs from our supplier on a selected amount of customers cars to check durability and working. No deviations are observed during the testing period and durability is generally checked. The MAFs are sold with a 2 year warranty giving the best feeling a customer can get about the product we are selling. Below a list of MAFs can be observed with cross reference to manufacture part number and prices.
