Standard Ignition VVT544 Engine Variable Valve Timing (VVT) Sprocket - Intake (Left)

Standard Ignition VVT544 Engine VVT Sprocket

The Standard Ignition VVT544 is an engine variable valve timing sprocket built for precise crankshaft timing control. It is a metal, single-row sprocket with a keyway notch and four timing marks, made for direct-fit service on select INFINITI applications.

For drivers searching for an INFINITI M45 intake left VVT sprocket or an INFINITI FX45 intake left variable valve timing sprocket, this part number provides the correct OE-style configuration for the listed vehicles. Standard Ignition VVT544 is also referenced by part number VVT544 for straightforward catalog matching.

Key Features

• Engine variable valve timing sprocket for crankshaft timing applications
• Metal gear construction for durable service
• Single-row design with one mounting hole
• 46 teeth with four timing marks for timing alignment
• Keyway notch included for proper indexing
• Inside diameter: 1.13 in. (28.702 mm)
• Outside diameter: 3.56 in. (90.424 mm)
• Thickness: 0.32 in. (8.128 mm)

Detailed Description

Standard Ignition VVT544 is an engine variable valve timing sprocket engineered for the crankshaft side of the timing system. Its metal gear construction, 46-tooth profile, and four timing marks support accurate timing setup during service. The part is not adjustable and does not include hardware, so it is intended as a direct replacement component for the specified fitments.

This sprocket fits 2008-2010 INFINITI M45, intake (left), and fits 2008 INFINITI FX45, intake (left). If you are replacing a worn INFINITI M45 intake left VVT sprocket or servicing an INFINITI FX45 intake left timing component, VVT544 is the catalog number to verify. This part cross-references ECP1746 for the same application.

What It Helps Fix

• Timing chain or cam timing concerns related to a worn sprocket
• Engine noise caused by timing component wear
• Incorrect valve timing from damaged sprocket teeth or indexing
• Check engine light conditions tied to variable valve timing performance
• Service issues during timing system repair on listed INFINITI models

Installation Notes and Tips

Confirm engine position and timing marks before removal and installation. Because this is a crankshaft gear with a keyway notch, proper indexing is critical during assembly. Verify the sprocket matches the intake (left) application for the vehicle before final installation. Use the factory service procedure for timing alignment on the INFINITI M45 or INFINITI FX45.

Quality Assurance

Standard Ignition manufactures this VVT sprocket to meet the dimensional and functional requirements listed above, including tooth count, timing marks, and fitment-specific geometry. Always verify part number VVT544 against the vehicle’s engine configuration before installation.
