Valve Spring, BMW - E36, E39, E60, X3, X5, Z3, Z4, M52, M52TU, M54, M56

Valve springs wear out over time and lose their tension. This can allow the valve to "float" - stay open longer and not close quick enough. Cars that see a lot of track time or extended high RPM should have their valve springs (and retainers and keepers) inspected regularly. Replacing them during major freshening or overhaul will help ensure maximum performance.   

Extremely low stock alert! BMW discontinued this valve spring in 2024. There are only a few of the Genuine springs left in our inventory. We have partnered with valve spring supplier to make an exact copy of the Genuine spring. See our Related Items below.  

Looking for an alternative? After the sudden discontinuation of this valve spring by BMW, we started making our own OE-spec valve springs for this application. Check out our part # 11347504268.BW for a lower cost version manufactured exclusively for BimmerWorld by an OE supplier to BMW.

This is the stock valve spring for non-M E36 323is/328i, E46 323i/325i/328i/330i, E39 525i/528i/530i, E60 525i/530i, X3 2.5i/3.0i, X5 3.0i, Z3, and Z4 2.5i/3.0i. These are the M52, M52tu, M54 and M56 engines, which are all 24 valve 6 cylinders that share this same stock valve spring. 

This valve spring was previously listed under earlier revision part numbers, including 11341427676 (11 34 1 427 676), 11341748878 (11 34 1 748 878), and 11437527133 (11 43 7 527 133). This is the newest version, which includes any design or manufacturing improvements BMW may have made through the years.
