I think cospa is the best.

● Mounting parts: Intake suction kit, shift knob (spherical shape)

We have introduced an intake suction kit to eliminate the feeling of lightness peculiar to diesel, and I think that the cost performance is the best with tuning that can be done for 1 yen.


Introducing a sphere shape for the shift knob The AT has changed from a genuine cheap feel to a genuine leather shift knob that feels good against the skin.Increased motivation
I thought it was a part that I could install by myself due to the reduction of wages, so I installed it myself.It was installed relatively easily (about 30 minutes)
This is also a part for 1 yen, which is cheaper for car parts and is recommended as a product with good cost performance.
