SMN Intake Spacer Kit Mercedes AMG C63(s) M177 W205/C205/S205 GLC 63(s) AMG C253/X253

The SMN Intake Spacer Kit for the 4.0 V8 Biturbo 476 hp / 510 hp is a simple plug & play solution to noticeably increase the immediate engine performance and response without software adjustment. The efficient design starts exactly where the restrictions of the original intake are and eliminates them. By modifying the lower air filter box according to the enclosed instructions, the air intake area is from 3,800 mm² to over 10,000 mm² This and the use of sports air filters unleashes the maximum potential.

The restrictions of the original intake system lie in the cold air supply and the height of the lower air filter box. Due to the low height, the original paper air filter protrudes into the intake opening and significantly limits the cold air supply.

We recommend the use of sports air filters for maximum performance. For standard engines, a performance increase of approx. 20 hp be determined in performance-enhanced vehicles up to over 30 hp . The 100 – 200 km/h acceleration improves by 0.25 sec compared to the use of sports air filters without the SMN Intake Spacers.

The intake spacers are made from high-quality PA6-CF (carbon fiber reinforced nylon), which has outstanding thermal and mechanical properties and is therefore ideal for use in the engine compartment. In addition, it has a unique surface quality due to the high carbon content. The black screws and dowel sleeves ensure that the engine compartment looks the same as the original. Attention: This article is not approved for use in the area of ​​the StVO!
