On modern fuel injected vehicles the air/fuel ratio is controlled by high-tech sensors. These sensors are absolutely crucial to your vehicle's performance. The job of Subaru Forester mass airflow sensors is to determine the amount of air being taken into the engine and adjust the fuel mixture to optimize power and efficiency. If your Subaru Forester mass airflow sensor goes bad it can cause all sorts of problems from check engine lights to knocking and pinging. Here at Andy's Auto Sport we have a full selection of replacement Subaru Forester mass airflow sensors to solve all of your problems. From stock to high-performance our assortment of sensors is sure to meet your demands.

OEM mass airflow sensors are designed to work within certain parameters. However, if you have modified your engine, or even just the intake system, the increased airflow can exceed the limits of the stock mass airflow sensor and cause running issues. In addition, the factory mass airflow sensors can also be restrictive to airflow and hinder power in high-performance applications. Thankfully many companies have developed performance oriented Subaru Forester mass airflow sensors to solve these issues. With a high-performance mass airflow sensor you can keep your car tuned properly to ensure peak performance.

Q: Why buy a mass air flow sensor?
A: Aftermarket mass air flow sensors improve horsepower and torque. Replacing your restrictive stock air flow meter with an aftermarket mass air flow sensor meter gives immediate acceleration gains.
