Fittment is perfect. Indeed Sound inprovement. But is modest. Also because the Cla45 has à cold airbox from the factory. I noticed à little difference in throttle respons in the lower revs. Positive. I bet with a Race kat in the exhaust and à smoother complete exhaust syste, this filter wil get its real bennefits. Sound on low speed when you release your throttle is the greatest differencke. You can hear that the turbo trows back some pressure. I also noticed that its flows better because first few rides the engine needed to ajust itself. Stotter, holding back when you put down the throttle. Very little. But it did. After 2 à 3 rides. Everything perfect.

Excellent fit and very good product gives the car a bit more grunt.

I bought this for my 2017 CLA 45 AMG and it fits perfectly, just like the stock one. I do not know about power gains but it does sounds a bit angrier when I hit the gas. I do wish that K&N would make a true intake with a tube adapter from the factory box to the turbo.
