High‑precision Exhaust Valve for Nissan Engines ?

This heat‑tough poppet controls the “exhale” of your motor. It seals the combustion chamber during the power stroke, then opens on time to release burnt gases. A correct, tight seal keeps compression strong, improves torque and MPG, and helps pass emissions ?.

How it works ⚙️

The camshaft lifts the valve via rocker/lifter to open flow. A coil spring snaps it shut so the faced head sits square on the seat. The slim stem guides true inside the head, while heat‑resistant steel survives red‑hot exhaust. Precise geometry ensures quiet operation and long life.

Why you need it ✅

• Restores compression and smooth idle
• Improves throttle response and fuel economy
• Protects catalyst by reducing unburned fuel

When it’s failing ❗

• Hard start, misfire, or rough idle
• Loss of power, poor MPG, ticking noise
• Popping in exhaust, high temps, MIL on

Driving with a burnt or bent valve can damage the seat and head, raising repair costs. Replace during head service or at the first signs ?️.
