Description
Here we present FMCT5, a twin catch can and coolant expansion tank system for the Hyundai i30N, Veloster N, and Kona N. This design has been subject to a vast amount of development and is a one of a kind product in the marketplace. This part has been developed in conjunction with our work on the BTCC championship winning Hyundai i30N’s – read more here
The FMCT5 is a direct replacement for the OE coolant expansion tank. The CAD laser cut alloy construction is skilfully welded at Forge UK HQ. The expansion tank has a level indicator inside the filler neck, to make topping up easier, we have also machined a cap cover that slots over the top of the OEM cap to add to the premium look.


The twin catch can system is the definitive solution to effectively reduce sludge and carbon build up, in turn allowing the engine to both breathe and perform more efficiently. It can therefore be viewed as a genuine performance enhancing product and one, we recommend, particularly if you are planning more advanced power tuning in the future.

Our system filters both PCV and intake breather systems to help keep your engine clean from harmful contaminants, including oil deposits, unused fuel vapours and moisture, which would ordinarily make their way back through to the inlet of the engine. All of this is now collected in the catch cans.

There is a dip stick for each tank to measure the amount of deposit caught, this opening can also be used to pump out the captured contaminants or alternately you can use the drain plugs at the bottom of the tanks.
As with all Forge Motorsport products we have used superior braided hoses which are internally constructed from anti-static smooth fuel resistant nitrile rubber. This is combined with an outer cover made from reinforced stainless-steel wire braid (a Forge specialty), specifically a partial inner braid and a full cover outer braid. We developed this complex arrangement in order for the tank to be resistant to both pressure expansion and vacuum collapse, and also to enable the kit to function within a clearly defined temperature range – 54°C to +150°C (-65°F to 300°F).
FMCT5 has now been developed to be compatible with Hyundai Veloster N and Kona N, as well as still fitting the i30N Mk3, and Mk3.5 (facelift). This product is available in our stealthy textured black powder coat finish.
