This is a genuine TOYOTA valve shim, part number SU00300247, designed to meet the exact specifications of your vehicle. Proper valve adjustment is crucial for maintaining engine efficiency, power output, and smooth operation. Valve shims are small, hardened steel discs that sit between the camshaft and the valve tappet, and their precise thickness is used to set the correct valve clearance. Over time, or after engine work, valve clearances can drift, leading to decreased performance, increased fuel consumption, and potential engine damage. Replacing or adjusting valve shims with this genuine TOYOTA part ensures that your engine's valvetrain operates within its designed parameters. This specific shim is manufactured to TOYOTA's high standards for durability and accuracy, providing a reliable solution for maintaining your engine's health.
