Supertech Nissan VG30DE/VG30DET Inconel Exhaust Valve - +0.5mm Oversize - Set of 12

If you're rebuilding the top end of a Nissan VG30DE or VG30DET engine, these Supertech Inconel exhaust valves are a solid choice. This set includes 12 valves, each measuring 0.5mm oversize to help restore proper sealing in worn valve seats. They are specifically made for these popular Nissan V6 engines, often found in performance applications.

Inconel is a high-nickel alloy known for its exceptional strength and resistance to extreme heat, making it ideal for exhaust valves that endure significant thermal stress. This material helps prevent valve distortion and burning, which is crucial for maintaining compression and engine longevity, especially in boosted or high-performance VG30DET applications. The +0.5mm oversize dimension means these valves are slightly larger than stock, designed to compensate for wear in the valve guides and seats, ensuring a good seal when installed.

When installing these valves, ensure your valve guides and seats are properly machined to accept the oversize dimensions. This set is designed to be a direct replacement for the stock exhaust valves, simplifying the rebuild process.
