ARM Motorsports N63R/TU2/TU3 CHARGE PIPES

The ARM N63R/N63TU2/N63TU3 Charge Pipes are engineered to increase airflow and provide methanol injection capability for BMW’s latest 4.4L twin-turbo V8 platforms. Designed to replace the restrictive plastic OEM pipes, these charge pipes allow you to safely inject methanol pre-intercooler—reducing intake air temperatures, supporting higher boost, advancing timing, and helping prevent detonation under demanding tuning conditions.

Perfect for N63R-equipped models such as the G30 M550i, G11/G12 750i, G14/G15/G16 M850i, and the X5/X6/X7 M50i variants, these charge pipes support both OEM turbos and OE-style upgraded turbochargers. For vehicles running elevated boost levels or performance calibrations, the added cooling effect of methanol injection can unlock substantial gains beyond what primary fueling can achieve alone.

Constructed from precision CNC-machined 6061 aluminum, the charge pipes deliver exceptional strength and durability. Each set includes 6-layer reinforced silicone couplers rated to handle over 40 psi of boost, ensuring reliable operation even under extreme performance conditions. Methanol ports are positioned immediately after the turbo outlet and before the silicone couplers—ideal placement for efficient cooling of the charge air before it enters the intercoolers.
