Cometic 90-94 Nissan SR20DE/DET DOHC 16V 2.0L Intake Valve Stem Seals

Made from a durable fluoroelastomer material, these Cometic intake valve stem seals are built to handle the heat and stress inside your engine. When your valve stem seals start to go, you'll often notice blue smoke puffing out the exhaust, especially on startup or when you let off the gas. That's oil leaking past the worn seals and burning in the combustion chamber. Replacing them is a key part of rebuilding the top end of your engine, ensuring a clean burn and preventing unnecessary oil consumption.

This set is designed to fit a range of Nissan and Infiniti vehicles from the early 90s, including models like the Infiniti G20, Nissan 200SX, and Nissan Maxima. They are a direct replacement for the original seals, meaning they fit right into the factory valve guides. Proper installation is crucial for their function, so make sure you have the right tools to compress the valve springs and remove the old seals without damaging the valve guides.
