Where is unit located on engine?DonnieOct 15, 2023
Best Answer:Hi Donel, I'm glad to assist you. The mass airflow (MAF) sensor is located between the air filter and the engine's intake manifold in most vehicles. It is a small, cylindrical device that measures the amount of air entering the engine. If your car appears in the vehicle fitment information below, it is a guaranteed fit part (select year, make, model, submodel, and engine size, the green round badge with a white check mark confirms a match). Grab our lowest price and click the link below to buy it today.
