The extra power you need when you need it: on the ramp acceleration, on demand passing, towing, through the hills or wherever. Granatelli Motor Sports performance mass airflow sensors reduce engine load and improve efficiency. This occurs by providing quicker and more accurate calibration to changes in engine intake airflow, fuel and spark timing. In addition, the smooth design of our sensor’s inlet tube improves airflow capacity over OEM equipment by an industry leading 47%. The added performance is chassis dyno proven from 2000 rpm to the red line. Most importantly, the performance can be felt where it counts, in the seat of your pants. Granatelli Motor Sports performance mass airflow sensors are ideal for adding extra performance with none of the hassles. All you need are basic hand tools and about 10 minutes of your time. Just follow the included step-by-step instructions and you’ll be enjoying an extra 10-23 rear wheel horsepower in no time. Now that’s performance, quick and easy!

MAF Sensors are only available in Black and also available with tuning for cars with cold air induction (*see explanation below) or a NOS dry kit.

*Cold air inductions significantly increase airflow and can cause tremendous turbulence in the air intake stream. When using the GMS mass airflow sensor with any type of cold air induction, high flow induction, or high flow air filter, your GMS mass airflow sensor must be calibrated with cold air tuning or a check engine light can occur. A “C” as the last digit in the part number designates cold air tuning.
