Hyundai i20 N (BC3 2021+)

Our Stage 1 (CT400) package rather than a tune alone. It is a race pipe (or a cat-back) to remove the restrictive secondary cat, one-step-colder spark plugs, an intake, and an intercooler resonator delete, finished with the tune. The secondary cat is the single biggest restriction on these 1.6Ts - we have measured gains from deleting it before a tune even goes on; the colder plugs keep cylinder temps in check as power climbs; the intake and resonator delete free up flow cheaply; and the tune ties it all together.

With our Stage 1 (CT400) package you can generally expect a gain of around +35kW and +55Nm at the flywheel.

Stage 2 (CT450) adds a downpipe and intercooler; a hybrid turbo opens up much bigger numbers with supporting fuel and clutch work.
