After taking it to the dealer, when I returned it, the air filter was about to come off and it was virtually filterless, but I decided to replace the filter because I couldn't forget how good it was blowing up at that time.
I can't change the box shape or piping due to the competition I'm participating in, so this is the only intake system.
As a result, the low-speed torque has increased, and the response when stepping on the accelerator has improved considerably.
Especially when starting from low speed 1000 rpm to 2 to 3000 rpm, it started to blow up comfortably.
Torque increases at higher rpm.
I think this effect is very cost performance at 1 yen.The replacement guideline is 2 km, which is enough.

The brake pads have also been changed from the stock ones, but the braking force has increased, and after stepping on the brake pedal, the more you step on it, the more it works.The color of the pad is also red, which makes it a dress-up color.
Last year it was in stock condition, and this year I ran Twin Ring Motegi after replacing it.
30km more speed at the end of the back straight thanks to the improved rise and the rear brake point.
