Static electricity builds up in the air intake while driving, disrupting airflow and engine efficiency.
AdPower absorbs this charge with its patented layered structure, improving airflow and keeping the engine in an optimal low-charge state.
We carry out measurements on a diverse range of vehicles with chassis dynamometers.
Many users who have actually used AdPower have commented on how effective it is.
Our products are highly rated in Japan, the United States, Australia, Singapore, and across the globe.
I can feel the idling of the engine is quieter and the acceleration smoother. Good product and money well spent.
Definitely filling the difference on cold start. Misfiring almost gone.
This small wonder just work..I've installed in several of my bikes from a small cc yamaha nouvo scooter to my z900rs and instantly felt the improvement, response definitely swifter and better. Good product indeed highly recommend.
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 .
Check the number of required sheets and installation location on the official website.
The air cleaner box(air filter cavity) is located near the engine itself and is shaped like a box with a hose-like air duct.
Remove the double-sided tape on the back of AdPower and attach it over the air cleaner box. Wipe the surface with a dry cloth before applying for better adhesion.
If the top of the air cleaner box is too rough to install, please install it on the side
※ The effect will not change.
Please note that once the product has been applied, it is fixed and cannot be reapplied.
If more than two pieces are required, please install them in separate locations.
The effect varies depending on where you stick it.
Please feel free to contact us for advice on the best placement of AdPower on your vehicle.
A:
AdPower helps suppress static electricity inside the air cleaner and throughout the vehicle. By reducing static electricity that interferes with smooth airflow, it helps lower air resistance and improve overall engine performance.
Based on feedback from our customers, many have experienced:
Smoother throttle response, even at low speeds
Improved acceleration feel
Reduced engine vibration and noise, resulting in a quieter ride
More stable idling
A smoother driving experience
A:
Many users notice a difference immediately after installation. However, depending on the vehicle and driving conditions, some may not feel the change during everyday driving and instead notice it more clearly when driving uphill or on highways.
A:
In the following situations, the effect may be less noticeable:
Driving on rainy days
If the driver is generally less sensitive to changes in driving feel or vehicle response
A:
While many users do notice improvements, the degree of effect can vary from person to person. The perceived results may differ depending on factors such as:
Vehicle type and characteristics
Engine condition
Everyday driving style
Throttle input habits
The driver’s sensitivity to changes in driving feel
Because of these factors, the level of improvement experienced may vary.
A:
AdPower does not guarantee the following results:
A significant numerical increase in horsepower or torque
Clearly measurable improvements in acceleration times
Repairing mechanical issues or poor vehicle maintenance
Guaranteed improvements in fuel efficiency
No. AdPower does not cause any negative effects on the engine when used as instructed.
A:
No. AdPower is a supplemental product and is not a substitute for regular maintenance. You are more likely to feel the benefits when basic maintenance is properly performed, such as:
Replacing the air filter
Changing the engine oil
Maintaining proper tire pressure
Keeping spark plugs and the fuel system in good condition

As of October 18, 2024
Research at Tokai University in Japan revealed that static buildup in the air cleaner box disrupts engine airflow. AdPower discharges this static, restoring smooth performance.
Ongoing studies at Chiba Institute of Technology in Japan further verify its effects.
*Results may vary depending on temperature and humidity conditions.
*The improvement in intake airflow due to static suppression was verified through experiments conducted at temperatures of 23.5–24.4°C and humidity levels of 51.2–59.2%.
AdPower is certified the efficiency.
