Jet Performance 69149 Mass Air Sensor The Jet Performance 69149 Mass Air Sensor is a product that helps to improve the performance of your vehicle's engine. The product has received mixed reviews from customers. One customer stated that they have seen an improvement in their gas mileage since using this product. They also mentioned feeling better about how their engine operates. Another customer shared their experience with a "running lean" issue that they had been facing for two years. They found that the local Mazda dealership was not addressing the issue and instead kept charging them for different "causes." The customer took matters into their own hands and replaced the sensor with this aftermarket one. They were satisfied with the results. However, not all customers had a positive experience. One customer with a heavily modified vehicle shared that the vehicle would not run unless they had the MAF unplugged or got a tune. They found that the vehicle ran with the stock MAF, but after installing this aftermarket product, the vehicle would not run at all. Another customer had issues with the product throwing an engine light just after two starts, and a rough idle that could not maintain 750 RPM. They had previously used this product two years ago and had a good experience, but when they purchased it again, they found that the "bulb" was smaller than the original, and the product did not feel right. Overall, the Jet Performance 69149 Mass Air Sensor has received mixed reviews from customers. While some have found that it improves engine performance and gas mileage, others have experienced issues with it not working correctly on their vehicles.
