222122B000 Hyundai / KIA VALVE-EXHAUST, Price: 4.78$, Weight: 0.04kg

Exhaust Valve OE-spec for Hyundai–Kia engines ?

This heat‑resistant exhaust valve lets hot gases exit the cylinder cleanly and keeps a tight seal on the seat when closed. Built from high‑temperature alloy with a precision-ground face and hardened stem tip, it protects compression, power, fuel economy, and emissions. Perfect fit and flow restore factory performance ?

Why you need it

A fresh valve maintains cylinder sealing, prevents hot spots, and preserves catalytic converter life. It’s essential after overheating, detonation, high mileage, or head work.

How it works

The cam opens the valve during the exhaust stroke; the spring closes it to seal against the seat. Heat transfers from the valve head into the seat and guide. Correct stem-to-guide clearance and face angle ensure long life and stable idle.

If the valve fails ⚠️

Expect misfires, loss of power, rough idle, backfire, hard starts, high fuel use, and possible P030x codes. A burnt or bent valve causes low compression and can overheat the catalyst.

Fitting tips ✅

Always inspect seat concentricity, lap if required, measure stem/guide clearance, replace stem seal and keepers, set valve clearance (or lifter preload), and follow head torque specs. Replace in sets for even flow ?
