More power for your Mercedes SL400

With the CPA PowerBox up to 61 HP additional power

We felt the Mercedes SL as absolutely suitable for everyday life. The double-charged 3.0-liter-V6 engine has a good draft and an excellent sound in our opinion. Our engineers have performed detailed work on the engine specific software. Although the performance increase in percent is not particularly a highlight at first sight, but an additional 61 hp increase with a series performance of 367 horse power is nevertheless a lot we think.
