  • Easy to install

    The air cleaner is located near the engine and is shaped like a box with an air duct.

    1. Find the air cleaner. The air cleaner is located near the engine body and is a box with a hose-like air duct.

Manufacturing Story

We established the"Tomizawa Fund" in 2007 and started a business.
However,the year after the establishment, the financial crisis provided an opportunityto transform the business, and I was thinking about how to restart it. At thattime, I visited Asian countries for the first time in a long time …


2020/11/21 Purchase the second piece

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 the cost performance is good.I want to buy another one for 2,000 yen.

2019/10/5 I was impressed!

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.

2020/8/7 Buy 2

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!

2020/12/10 First report

The car is a Mazda Flair Wagon (OEM car of Suzuki Spacia) registered in March 2018, and is a light car with a current running speed of 50,000 km.I feel that the torque has increased in the experience part. Is it a feeling that the car goes out in front with less stepping than before? I felt it when I was riding in the city before a business trip, but I felt it stronger when driving at high speed. The fuel consumption on the outbound route was almost the same as 22km / l, but in fact, the travel time to Osaka has been shortened by more than 30 minutes. In other words, I was driving at an average speed of about 10km / h higher than before. Since it is a box-shaped car, the fuel efficiency was extremely poor when driving at about 100 m / h or higher, so I think that the fuel efficiency part was also effective.

2020/10/18 Fuel economy has improved

It is a verification with RG1 of Step WGN that runs over 200,000 km. I think it will change depending on how you drive and the presence or absence of traffic lights, but the old fuel consumption was 10.5-11.0 km, but now it is 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.

2021/2/7  I put it in secret

I put it on my wife's car in secret.Two weeks after I put it on, my wife muttered, "The car is in good shape recently."She shouldn't know what I put on ...It may be effective.
