When accelerating, a fat sound that is lower than the normal sound is now produced.

● Mounting parts: Sports induction box, intake suction kit, sports plug cord

I installed three parts at the same time.What you can clearly see is the change in the intake sound.When accelerating, a fat sound that is lower than the normal sound is now produced.I didn't feel the lower torque phenomenon that I was worried about.I'm satisfied.
Also, since I changed the plug to a new one at the same time as the plug cord, it can not be said that the effect of the plug cord is unconditional, but it does not misfire when idling.
