I used to have a chamber made by another company, but since it was a diesel car, the DPF spacing caused problems.
However, after installing AutoExe's intake suction kit, I had no problems idling, and the DPF interval has stabilized.

Also, unlike the original shape, there is no bellows, so it feels like it can suck in a lot of air, the engine revs up well, and you can hear the intake noise, which motivates you.
It's a product that I'm glad I bought.
