How AdPower Works

Benefits of AdPower

What is AdPower?

Static electricity builds up in the air intake while driving, disrupting airflow and engine efficiency.

AdPower reduces this charge with its patented layered structure, improving airflow and keeping the vehicle in an optimal low-charge state.

Visualizing AdPower’s Static Electricity Reduction Effect

Why the Engine and Door Hinges?

We focused on two areas where static electricity tends to accumulate while driving.

AdPower for Door Hinges discharges static electricity generated by tire friction and air friction around the side mirrors, while AdPower for Engines discharges static electricity around the vehicle body and engine.

By discharging it, AdPower helps improve airflow around the vehicle.

Good product

I can feel the idling of the engine is quieter and the acceleration smoother. Good product and money well spent.

Try it to believe it

Started to use more than a year ago and has not stopped since . You can feel the difference immediately after you stick it. The different in acceleration and the overall weight of the car as compared to before. Good product. Worth the money spent. Try it believe it .
