Original Technology

Suppress the static electricity in the air intake, the engine combustion improves.

The effects are:
1. Output (horsepower/torque) improvement.
2. Exhaust gas reduction.
3. Fuel efficiency improvement.


AdPower is certified the efficiency by many organization.

Comparison test of fuel consumption and exhaust gas amount

By way of comparison test conducted by  the authorities, it had been confirmed that fuel efficiency was improved and CO and NOx contained in exhaust gas were reduced.

Fuel consumption rate:.
2017-2018 Average measurement test values ​​at public institutions and manufacturers.

Exhaust gas emissions:Association of Travel AgentsTest on October 15-16, 2018

The effects just by sticking

Engine performance goes up

The moment when you put the AdPower on ,your engine performancer  goes up.

Fuel economy

To improve combustion efficiency and fuel economy.

Reduce Exhaust gas

To reduce the quantity on NOx and CO includeo in an exhaust gas.

We have stucked 2 pieces of these on a 2500cc V6 car.

There is an improvement in torque and smooth acceleration from low to medium speed.
The cost effectiveness is good for this kind of change at this price.

We added two more for the car and two for the motorcycle to surround the tunnel in front of the airbox. This is to let the intake air come in contact with adpower as much as possible.
By this construction, the torque from low speed range was improved considerably.


I bought 3 of these for my 4400cc engine.
I put them on the outside of the filter for fear that they would come off. I felt the smoothness and the lightness of the air.
However, in the second picture, the part I put on top was hidden when I put the filter back.
I got the confirmation that there was no problems, but it looks good so I bought another one to install. 
I feel like it blows up lighter and goes on smoothly and quietly.
My previous car was a 4400cc car with the Ram Air system and it feels as good as that one.
For the price of this car, it feels great.
I think there is a synergistic effect of the sports filter and 4 protruding mufflers.
The manufacturer's response and explanation of the product was very good and satisfactory.


This car is a BMW 320i.
I put two of them in the box.
My impression of driving in ECO mode is that when I stepped on the accelerator at a traffic light, I felt like I was in the wrong place.
When I step on the gas pedal as much as before, it moves forward with more force than before I put it up!
Now we just have to hope for better gas mileage!


It is the 3rd day after pasting, but it is effective for torque at the time of starting and engine braking with accelerator off. Since the engine brake does not work, it rolls well.The torque is also up and the number of revolutions is down.I don't know the fuel consumption yet, but 8.6 has increased to 9.1.I think it's worth more than the price, so I want to buy another one.I pasted it on the engine side with our rk5 Step WGN. When peeling off after 2 years, replace the double-sided tape, buy a new one, and stick it on the engine side.What I can say now is that I will definitely buy it two years later.


This kind of product has existed for decades, but I hadn't seen it featured in a magazine in a long time, so I bought it. It is a simple product to put in the air cleaner box, but the result came out from the first 60km after the installation. The fuel consumption which was 11km/liter at best until now has increased to 13.1km/l. 

The sound changes immediately after installation, and the change is immediately felt, so it is the best product for the price. There is no need to buy expensive goods.


It is a verification with RG1 of Step WGN that runs over 200,000 km. I think that it will change depending on how you drive and whether there is a signal, but the old fuel consumption was 10.5-11.0 km, but when AdPower was pasted, it became 12.2 km. Since it is an in-vehicle fuel consumption meter display, it is just a guide, but I was happy because the mileage exceeded 600 km from the full tank to the next refueling, so I ordered additional parts for light cars and motorcycles.


Super Taikyu is an automobile race held in Japan. A machine that has been modified from a commercially available four-wheeled vehicle will participate. AdPower is also used in Super Taikyu.
