PROFILE


The ARM MK8 Bi-Cooler Piping Upgrade is constructed fromĀ 6-layer steel-wire-reinforced silicone, capable of handling overĀ 50 psiĀ of boost pressure. To ensure a secure, leak-free connection, the system is supplied withĀ constant-tension T-bolt clampsĀ that maintain consistent clamping force through heat cycles and high-boost conditions.
Throughout the entire system, the ARM MK8 Bi-Cooler PipingĀ maintains a consistent 2.5" diameter.Ā This sizing is engineered to maximize airflow volume while preserving charge-air velocity for strong throttle response and efficient turbo operation. In testing, the bi-cooler configuration proved extremely effective, with intake air temperatures remaining close to ambient even under demanding conditions when pairing theĀ ARM MK8 FMICĀ with the factory intercooler.
IN THE BOX
⢠2x ARM MK8 Bi-Cooler HosesĀ
FITMENT GUIDE
The ARM MK8 Bi-Cooler Piping Upgrade is designed to work specifically with theĀ ARM MK8 FMIC.
