Timing Chain Tensioner

The BMW Genuine Parts 11317584723 is an OEM timing chain tensioner, crucial for maintaining proper chain tension within specific BMW engines. This part is manufactured by Jwis, the original supplier to BMW for this component, ensuring it meets all original design, fitment, and performance requirements. It is TUV approved and offers a more affordable alternative to Original BMW parts while maintaining near-identical quality. This timing chain tensioner is designed for a range of BMW 3.0L engines, including naturally aspirated N51 and N52, as well as turbocharged N54, N55, and S55 variants.
