If your Toyota Corolla (2002-2008), Matrix (2003-2006), or Celica (2002-2004) needs a new PCV valve, this one’s a solid pick. It matches OE number 12204-22051, so it’s designed to fit right in. Made from sturdy metal with a heat-resistant and chemical-resistant build, it ensures a good seal and reliable performance. Why replace your PCV valve? Well, it helps reduce emissions, prevents pressure buildup in the crankcase, minimizes oil leaks, and stops sludge from forming – basically, it keeps your engine happier. Installation’s straightforward: locate the old valve on the engine, remove it, pop this one in, and reconnect any hoses. Just double-check it fits your model before buying (it’s non-OEM, but made to spec). The green color makes it easy to spot, and it comes as a single valve in the package. No fuss, no leaks – just a dependable part that does its job. Keep your engine running smoothly with this simple upgrade.
