Supertech Toyota 2JZ Inconel Exhaust Valve - +1mm Oversize - Set of 12

Crafted from Inconel, a high-nickel alloy known for its exceptional strength and heat resistance, these Supertech exhaust valves are built to handle the demands of a high-performance Toyota 2JZ engine. Each valve is precisely machined to a +1mm oversize, which can help restore compression and improve sealing in engines with worn valve seats or guides. This set includes 12 valves, enough for a complete engine rebuild.

The Inconel material is crucial for exhaust valves because it can withstand the extreme temperatures and corrosive gases found in the exhaust port, helping to prevent valve distortion or failure under high-load conditions. The +1mm oversize dimension is a common solution when rebuilding a 2JZ, allowing for a fresh seal against the valve seat. This attention to material science and dimensional accuracy means these valves are a solid option for enthusiasts looking to maintain or enhance their engine's performance and longevity.
