Supertech Nissan 240SX KA24DE Inconel Exhaust Valve - +0.7mm Oversize - Set of 8

Made from Inconel, a high-nickel alloy, these Supertech exhaust valves are built to handle the extreme temperatures found in performance Nissan 240SX KA24DE engines. This set includes eight valves, each precisely machined to be 0.7mm oversize, which is crucial for rebuilding or upgrading an engine where the valve seats may have been reconditioned or enlarged. Inconel's inherent resistance to heat and corrosion makes it a top choice for exhaust valve applications, especially when you're pushing the limits of your engine.

When you're rebuilding the top end of your KA24DE, using valves that can withstand the harsh exhaust gas environment is key to long-term reliability. These Supertech valves are well-built and designed to maintain their integrity under high heat, helping to prevent valve seat recession and ensure a proper seal. The +0.7mm oversize dimension means they are intended for engines that have had their valve seats machined to accommodate this larger size, offering a fresh, tight fit.

If you're working on a performance build or a thorough engine overhaul for your Nissan 240SX, these Inconel exhaust valves are a solid option. They are designed to be a direct replacement for the stock valves, assuming the valve seats have been prepared for the oversize fitment. Ensure you have the correct tools and procedures for valve installation, as proper seating is critical for engine performance and longevity.
