Detailed Description

Standard Ignition VVT550 is an intake variable valve timing sprocket used on select Nissan Altima, Murano, Pathfinder, and Quest models. This part number, VVT550, is specified for 2014-2018 Nissan Altima intake applications and 2015-2016 Nissan Murano, Pathfinder, and Quest intake applications. It cross-references Standard Ignition VVT550 and related aftermarket numbers such as 35-1348 for the same application. The metal gear design, 52-tooth profile, and timing marks support precise cam timing service on engines that use a crankshaft-style sprocket layout.

• Incorrect intake cam timing after sprocket wear or replacement
• Timing mark alignment issues during valve train service
• Engine performance concerns tied to variable valve timing operation
• Noise or irregular operation from a worn timing sprocket
• Service replacement for a damaged or corroded VVT sprocket

Installation Notes and Tips

• Verify the intake-side application before installation; this part is not adjustable.
• Align the keyway notch and both timing marks exactly to the engine service procedure.
• Inspect related timing components, seals, and fasteners before reassembly.
• Confirm fitment for 2015-2018 Nissan Altima intake, 2015-2016 Nissan Murano intake, 2015-2016 Nissan Pathfinder intake, 2015-2016 Nissan Quest intake, and 2014 Nissan Altima intake from 5/14.

Quality Assurance
