Keep the camshafts and crankshaft turning in precise time with the INA timing chain kit ZC0027K, a premium-grade upper timing chain set for BMW inline-six engines. It installs as a direct-fit replacement across a wide range of applications, including the 2004-2006 BMW X3, 1997-2002 BMW Z3, 2003-2005 BMW Z4, 2001-2006 BMW 330Ci, and 2001-2006 BMW X5, covering the L6-2.5L, L6-2.8L, and L6-3.0L engines — see the Buyer's Guide tab for the full list of 24 applications.
The timing chain links the crankshaft to the camshafts so the valves open and close in step with the pistons; the included tensioner maintains proper chain tension while the guides keep it tracking quietly. A stretched or worn chain, a failing tensioner, or worn guides can produce a rattling noise at cold start or timing-correlation trouble codes. If a worn upper timing chain, tensioner, or guide is the cause, this kit replaces those components.
