OEM‑grade Exhaust Valve for Nissan Engines

Why you need it

This exhaust valve seals the combustion chamber and releases hot gases on time. A tight seal keeps compression high, power strong, fuel use low, and emissions clean. It also protects the cylinder head and catalytic converter from heat stress.

How it works

Driven by the cam through a rocker/lifter, the valve opens to let spent gases exit, then a spring snaps it shut. Its hardened face meets the seat at a precise angle for a gas‑tight seal. The heat‑resistant alloy, chrome stem, and guided movement control temperature and wear, carrying heat into the head and cooling system.

When it fails ⚠️

Burnt edge, bent stem, or stuck valve cause low compression, misfire, rough idle, loss of power, backfire, and hard starts. Ignoring it can overheat the catalyst or even chip the piston—costly damage. Replace in pairs or full set, check guide clearance, lap the seat, fit new stem seal, and verify timing/valve lash after install.

Built for long life ✅

Precision seating, corrosion resistance, and stable spring control deliver quiet operation and strong engine health.
