Was going to buy cheaper ones that look like K&N from Walmart. Appearance did not look like the same quality as K&N. I figured for the price don't be cheap with the air intake on our Mercedes. Get what you pay for.....

Easy to follow instruction, increased horsepower and sound better, no dyno test but felt more power and torque compare to prior to installation.

I have always replaced the stock air filters in all of mycars withthe Kand N filters. I have always noticed slight improvement in performance and a cooler running engine. This time ireplaced the filters in my 2009 C63. And immediately saw a drop of engine temp of about 15'F. In the middle of summer with AC on. As for performance wel the car makes 451hp as is but it definetlyfelt better. Instalation was very easy. Highly reccomend them to everyone witha car or truck.
