47 percent more airflow than stock!
Granatelli Motor Sports offers these innovative mass airflow sensors as an upgrade for your stock one. The sensors feature state-of-the-art hybrid electronics, which provide improved ignition and injector timing control, resulting in a 10-15 HP gain at the rear tires. They're easy to install, and they're housed in a rugged injection-molded body to reduce heat soak, a common problem with stock metal sensors.
