Supertech Opel/Vauxhall Z20LET Inconel Exhaust Valve (Use w/KPR-6S/7) - Set of 8

These are Supertech Inconel exhaust valves designed for the Opel/Vauxhall Z20LET engine. This set includes eight valves, which is what you'll need to replace all the exhaust valves in your engine. They are specifically made to work with KPR-6S/7 valve springs.

Inconel is a high-nickel alloy known for its exceptional strength and resistance to extreme temperatures. This makes these valves a solid option if you're rebuilding the top end of your Z20LET, especially if the engine sees hard use or higher boost levels. The material helps prevent valve distortion and burnout under high heat conditions, which can be a concern with stock valves in modified applications. They are well-built to handle the demands of performance engines.
