DeatschWerks was the first to market with a 100% drop-in fitment injector for the new GT-R. We know the GT-R is a special machine. That is why we take our level of perfection to a whole new level for this application. We hand balance each set individually both statically and dynamically to a 1% or less variance. Our injectors recently propelled the AMS GT-R to a record setting quarter mile time of 10.48@134mph.
