acceleration.

Silky Shift

The specially tailored formulation makes shifting feel smoother so you can concentrate on driving.

Nano Silky Tech enables smooth upshifting even at a high speed. So you feel less stress when accelerating hard during spirited driving.
Silky Shift Formula

Our proprietary Silky Shift Formula, achieved with cutting-edge nanotechnology, reduces frictional resistance between metals.
Evaluation of friction
coefficient by MTM testing

Since the IRG 5 has a smaller coefficient of friction than competitor’s flagship products, it reduces friction between gears and enables smooth upshifts.
