Keep camshaft timing accurate and quiet with the Standard Ignition Engine Variable Valve Timing (VVT) Sprocket VVT529. Cataloged as the left-bank sprocket, it serves as a direct-fit OE replacement and fits many vehicles, among them the 1998-2001 Toyota Corolla, 2003-2008 Toyota Matrix and 2003-2008 Pontiac Vibe — see the Buyer's Guide tab for the full list.
A VVT sprocket adjusts camshaft phasing so valve timing changes with engine speed and load. If a worn sprocket is the cause of rough idle or poor drivability, replacing it addresses that mechanically — diagnose the cause first, as those symptoms have other sources.
