GSC P-D Toyota 2JZ 21-4N Chrome Polished Intake Valve - 34.6mm Head (+1mm) - Set of 12

If you're working on a Toyota 2JZ engine, specifically in a 1993-2005 Lexus GS300, 2001-2005 Lexus IS300, 1992-2000 Lexus SC300, or a 1993-1998 Toyota Supra, these GSC Power Division 21-4N intake valves are a solid option. These valves are designed to be a direct replacement for your stock intake valves, but with a slightly larger 34.6mm head, which is 1mm over stock. This increased diameter can help improve airflow into the combustion chamber, potentially leading to better engine performance.

GSC Power Division makes these valves from well-built materials and they feature a chrome polished finish. This finish not only looks good but also helps with durability and smooth operation within the valve guide. The set includes 12 valves, which is what you'll need for a typical 6-cylinder 2JZ engine. When installing these, remember they are a direct fit, meaning no modifications are needed to the cylinder head itself, but you'll want to ensure your valve seats are in good condition to match the new valve size.
