The parking lot for my apartment building is a self-propelled multi-story parking lot, but the slope leading up to the upper floor is quite steep, so I had to go up in 1st gear or get up in 2nd gear.
When I try to go up normally in 2nd gear, the engine stalls.
After installing this intake suction kit, the low-speed torque increased and I was able to climb in 2nd gear.

I was impressed by this effect.
It also looks great as an accent inside the hood.
