The Masters at Eventuri have invested months of intensive research, development, and testing to create a beautiful and effective aftermarket chargepipe solution for your S55 powered BMW. Eventuri is the gold standard for carbon fiber performance upgrades, and these chargepipes are no exception. The three main criteria kept in mind during the design of these chargepipes was fitment, flow quality, and strength. The carbon fiber construction allows for complex geometry providing an OE like fit. The flow is increased over stock, sporting a constant diameter throughout the chargepipes. The strength of OEM chargepipes is poor, rendering them prone to failure. The cross-directional carbon weave on the Eventuri pipes are over 2mm thick, providing a reliable strength even with increased boost levels or larger turbos altogether.
