The Mercedes GLC63 intake system is the culmination of extensive development and testing. Our design brief consisted of 3 main objectives: 1) Increased flow rate. 2) Low intake temperatures. 3) Smooth airflow. The first objective was met by utilizing all of the limited space available in the GLC63S engine bay resulting in a 35% higher flow rate over the stock system. The second objective was met by designing a fully sealed system. The GLC63S engine bay reaches high temperatures with heat sources like the turbos in close proximity to the intake so it is crucial that the intake remains sealed. The final objective was met by designing an organically shaped system with custom rounded panel filters to ensure the airflow path contained no sharp corners and therefore allowed for the flow to remain laminar. With smooth transitions from the filters to the turbo inlets, our intake minimizes the formation of turbulence and therefore the turbos are able to operate more efficiently.

With all 3 objectives met, our GLC63 intake system delivers on all fronts and allows for the turbos to generate boost more efficiently. This results in an improved throttle response and genuine power gains which increase with higher states of tune. Since there are various turbo upgrades available for the GLC63S we have also catered a specific solution for larger turbos. Our GLC63S intake is available in 2 configurations: 61mm ID outlets to match the stock turbos and 76.5mm ID outlets to match larger turbos.
