Manley 90-96 Nissan 300ZX 3.0L (VG30D - VG30DTT) DOHC 24 Intake 35mm Stainless Race Flo Valves

If you're working on the engine of your 1990-1996 Nissan 300ZX, especially if it's a VG30D or VG30DTT model, these Manley Race Flo intake valves are a solid choice for rebuilding or upgrading. These are specifically designed for the 3.0L DOHC 24-valve engine, measuring 35mm in diameter, and are built to handle the demands of performance driving.

Manley constructs these valves from high-quality stainless steel, which is crucial for durability and resisting the heat and stress inside the combustion chamber. The stems are chrome-plated and the tips are hardened to resist wear, meaning they'll hold up longer. They've also been swirl polished under the head and fully machined on the faces to help optimize airflow into the cylinders, which can make a noticeable difference in how the engine breathes and performs, especially when you're pushing it past 8000 RPM.

These valves are a popular option for racers, and they're even recommended for use in alcohol-fueled engines for exhaust applications, showing their robust construction. If you're rebuilding the top end of your 300ZX and want parts that are built to last and perform, these Manley valves are worth considering.
