GRANATELLI 4.6/5.0/5.4 CARS & TRUCKS. HI-PERF SLOT-IN STYLE MASS AIRFLOW SENSOR

Granatelli offers innovative mass airflow sensors as an upgrade for your stock MAF. The sensors feature state-of-the-art hybrid electronics, which provide improved ignition and injector timing control that results in a 10 to 15 hp gain at the rear tires. They're easy to install and housed in a rugged, injection-molded body to reduce heat soak, which is a common problem with stock metal sensors.
