Granatelli Motor Sports

Have you changed the intake, camshaft or boost on your engine and need the air metering to keep up? Granatelli Motor Sports is an American brand best known for mass airflow (MAF) sensors for performance engines. Here you'll find MAF sensors and other engine parts for many popular American cars and trucks.

American specialists in air metering

Granatelli Motor Sports is an American brand focused on the part of engine management that measures the air the engine takes in. The brand is especially well known among Ford and GM enthusiasts, where many modified cars need a mass airflow sensor that can cope with more air and a bigger intake. Granatelli makes both calibrated sensors that fit the stock housing and complete meters with their own housing for higher airflow. The idea is to give the engine management an accurate signal, so the air-fuel ratio stays right after an upgrade.

Granatelli Motor Sports' key products

The core of the range is mass airflow sensors in several versions: slot-in sensors that fit straight into the existing housing, and complete MAF units in various diameters for larger intakes and boosted engines. Many are calibrated for specific engines and power levels, so they suit a modified engine better than the original part. The brand also offers other engine and ignition parts. It is important to choose a sensor that suits your engine, intake and tune. See each product for vehicle and engine fitment.

Frequently asked questions

Why should I change the MAF sensor after a build?

A stock MAF sensor is matched to the standard engine. With a bigger intake, camshaft or boost it may read incorrectly or reach its limit, so the air-fuel ratio goes off. A calibrated sensor can give the engine management a more accurate signal.

Does the engine need a tune after fitting a new MAF sensor?

It depends on the sensor and the rest of the build. Some sensors are calibrated to work without new software, while bigger changes often require a tune. Check the description on each product.
