I used to ride with a normal filter, but I bought DIESEL because I thought that if I took in a lot of air, the generation of soot would decrease.
The material is thinner than the normal filter and the filter itself seems to have good suction efficiency.
You can experience the impression after wearing it like this! The accelerator response has improved as much as ️. I also feel that the DPF interval has increased a little.
I'm a little worried that the red filter will be hidden after mounting and that it's disposable, but I think it's a good part because it improves the ride quality.
