ARM Motorsports Bi-Cooler Upgrade - Volkswagen GTI / Golf R (Mk8/Mk8.5) 2022-2025

ARM Motorsports Bi-Cooler Upgrade - Volkswagen GTI / Golf R (Mk8/Mk8.5) 2022-2025

HIGHLIGHTS

• Allows Utilization of Both ARM MK8 FMIC and OEM IC
• ImprovedĀ Cooling Ability
• Reduced IAT's
• 6-Layer Reinforced Silicone
• Constant Tension T-Bolt Clamps
Ā 

PROFILE

The ARM MK8 Bi-Cooler Piping Upgrade allows you toĀ run theĀ ARM MK8 FMICĀ in combination with the OEM intercooler, or any upgraded OEM-location intercooler that retains factory charge-pipe routing. This dual-intercooler configuration creates a true bi-cooler setup, significantly increasing overall charge-air cooling capacity while maintaining OEM-style fitment.

MK8 FMIC Bi-Cooler

Designed as the ultimate charge-air cooling solution for the MK8 platform, the ARM MK8 Bi-Cooler Upgrade utilizes a unique dual-cooling strategy that improves heat dissipation under sustained load.Ā By pairing theĀ ARM MK8 FMICĀ with the factory intercooler, intake air temperatures are reduced, cooling efficiency is increased, and thermal stability is maintained during aggressive driving, repeated pulls, or track use.

MK8 FMIC
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 
• 6x Constant Tension T-Bold Clamps


FITMENT GUIDE

The ARM MK8 Bi-Cooler Piping Upgrade is designed to work specifically with theĀ ARM MK8 FMIC.
