Nissan/Infiniti tuner Impul chose the Tokyo Auto Salon to make the public debut of its new 651S tuning package for the new Infiniti M luxury sedan.
While some of the aerodynamic modifications aren’t to out taste, thankfully Impul isn’t just some plastic-fantastic shop. They actually offer a full line of modifications.
Shown on this car is a spring and shock combo package, as well as a big brake upgrade with 6-piston front calipers and 4-piston rear. Added power comes thanks to a dual-exhaust system, as well as a retuned ECU and larger throttlebodies. Those upgrades are, however, only offered for the M37 and M25 models (yup, they have an M25 in Japan) and Impul has yet to announce any performance upgrades for the big-dog M56.
