Forge Motorsport FMCT5 Twin Catch Can and Coolant Expansion Tank System
Introducing the FMCT5, a twin catch can and coolant expansion tank system designed specifically for the Hyundai i30N, Veloster N, and Kona N. Developed in conjunction with Forge Motorsport’s work on the BTCC championship winning Hyundai i30N’s, this one of a kind product has undergone extensive development to ensure top-notch performance.
The FMCT5 is a direct replacement for the OE coolant expansion tank, featuring CAD laser cut alloy construction skillfully welded at Forge UK HQ. The expansion tank includes a level indicator inside the filler neck for easy topping up, along with a machined cap cover to enhance the premium look.
The twin catch can system is the definitive solution for reducing sludge and carbon build up, allowing the engine to breathe and perform more efficiently. It is a genuine performance enhancing product, especially recommended for those planning advanced power tuning in the future.
Our system filters both PCV and intake breather systems to keep the engine clean from harmful contaminants, collecting oil deposits, unused fuel vapors, and moisture in the catch cans. Each tank includes a dip stick for measuring the amount of deposit caught, with the option to pump out the captured contaminants or use the drain plugs at the bottom of the tanks.
Superior braided hoses internally constructed from anti-static smooth fuel resistant nitrile rubber and reinforced stainless-steel wire braid ensure resistance to pressure expansion and vacuum collapse, functioning within a temperature range of -54°C to +150°C (-65°F to 300°F).
The FMCT5 is compatible with Hyundai Veloster N and Kona N, as well as the i30N Mk3 and Mk3.5 (facelift). Available in raw aluminum finish or textured black powder coat finish.
