Detailed Description

Standard Ignition VVT547 is a variable valve timing sprocket for the intake right position on 2008 Infiniti FX45 and 2008-2010 Infiniti M45.

• Correcting cam timing reference issues during engine service
• Supporting repair on Infiniti M45 and FX45 VVT systems

Installation Notes and Tips

Verify engine position and timing marks before removal, and follow the factory service procedure for camshaft timing alignment. Because this sprocket uses a keyway notch and timing marks, careful indexing during installation is important for proper valve timing. Confirm fitment for 2008 Infiniti FX45 intake right and 2008-2010 Infiniti M45 intake right before ordering. Standard Ignition VVT547 should be installed only on the listed applications.
