The Mercedes-Benz CLK63 AMG is a remarkable creature, praised by those that have driven it and coveted by those that haven't. But even with its exemplary performance attributes and its remarkable amount of power, one can still pose the question: "Could the CLK63 AMG Black Series be better?" Judging by the latest work from Kleemann, the Danish tuner's response if asked the aforementioned question would be an unequivocal "yes." That's because the company has unveiled a series of tuning products aimed directly at making the already-spectacular CLK63 Black even more desirable, adding a number of subtle performance enhancements while maintaining the same everyday drivability we've all grown accustomed to in each and every one of AMG's various models.

How exactly did they do it?

so basically a little more power, some Kleeman badges, and a nice set of forged 20's? god knows what they are charging!

 

Wow! A 7 percent increase in HP! Wow!

The Shell Answer Man used to say if you drove with the A/C off, the windows rolled up and had your tires properly inflated you'd see that increase.

Wake me when they get 700 HP out of their CLK.

 

That is not a bad increase for a naturally aspirated engine with exhaust and a tune. Would have been nice to see the Kleemann with more mods though!
