Dial in precise exhaust-camshaft timing with the Standard Ignition Engine Variable Valve Timing (VVT) Sprocket VVT666. Mounted on the exhaust camshaft, this VVT sprocket (phaser) uses engine oil pressure directed by the VVT solenoid to advance and retard cam phasing so the valvetrain stays in step with engine demand. It installs as a direct-fit replacement across a long list of BMW L6-3.0L models — including the 2007-2013 328i, 2012-2015 335i, 2011-2016 535i, 2007-2018 X5 and 2011-2019 X6 — plus the 2015-2016 Z4 L4-2.0L. See the Buyer's Guide tab for the full list of applications.
Diagnose the source of any timing complaint before ordering, since these symptoms can have other causes.
What does this VVT sprocket do?
It sits on the exhaust camshaft and uses oil pressure directed by the VVT solenoid to advance and retard cam timing, keeping the valvetrain matched to engine speed and load.
Which camshaft position is this for?
VVT666 is cataloged for the exhaust camshaft position on the listed BMW applications.
Will this fit my BMW?
It fits many BMW L6-3.0L models plus the 2015-2016 Z4 L4-2.0L. Check the Buyer's Guide tab and match your exact year, model and engine before ordering.
What are signs this sprocket may need replacing?
A rattle on cold start-up, VVT or cam-timing fault codes, and rough running can point to a worn exhaust phaser. Confirm the cause first, as other parts can produce these symptoms.
How many are needed per engine?
The listed applications use one (qty 1). This listing is for a single VVT sprocket; verify your engine's requirement in the Buyer's Guide.
