Injen Hot-Side Charge pipes - F8X M3/M4

Injen Hot-Side Charge pipes - F8X M3/M4 These Injen Charge Pipes for the F80 M3 and F82/F83 M4 are smoother flowing than the stock, compressed plastic pipes. These pipes replace the hot-side pipes leaving the turbos and into the top-mount intercooler. These high-grade 6061-T1 aluminum pipes are mandrel bent for better flow, which helps reduce turbo lag and improve throttle response. The CNC-machined flanges have beaded ends to prevent the pipes from slipping off under high boost. All of the factory mounting points are retained for a direct replacement for the stock S55 chargepipes. Offered with either black or red wrinkle finish with the Injen logo and silicone couplers to the stock or most aftermarket top-mount intercoolers (including CSF). For bulletproof turbo piping and higher flow, Injen intake components are the total solution. BMW Fitments: 3 Series F80 (2015+) > M3 (2015+) 4 Series F82 / F83 (2015+) > M4 (2015+)
