KTW Mercedes-Benz C63 AMG pumps out 518-hp

So you own a ‘stock’ 451-hp Mercedes-Benz C63 AMG Coupe but you secretly envy those who recently purchased a 510-hp C63 AMG Coupe Black Series. It seems like German firm KTW Tuning may have a solution for you.

The tuning company has just released a new upgrade package for those that own the ‘standard’ C63 AMG Coupe and have a lust for the Black Series Edition. The tuning package pushes output to 518-hp and removes the electronic speed limiter so you can push your limits.

Styling wise, KTW adds a new black grille, tinted side and rear windows, and set of 20-inch lightweight alloy wheels wrapped in 235/30ZR20 tires at the front axle and 275/25ZR20 at the rear.

All those upgrades will run you about $8,500.
