Fix BMW N57 Intake Swirl Flap Issues Without Replacing the Entire Manifold!
Avoid expensive intake manifold replacement. This repair kit restores proper operation of the swirl flap linkage in BMW N57N and N57Z diesel engines, eliminating common issues like error codes, poor fuel economy, and reduced engine response.
Over time, the original intake rod and seals wear out, causing play in the mechanism and boost leaks. This kit provides a durable and cost-effective solution to restore correct function and performance.
Important Note: Please verify your engine code and OEM number before purchase to ensure compatibility.

Important Installation Note:
To achieve a precise zero-play fit, the hole in the replacement rod is intentionally made slightly smaller than OEM. Due to normal wear differences in actuator arms, light sanding may be required to achieve a perfect custom fit. This ensures maximum reliability and eliminates unwanted play.
