Fitment and details
When the N55 turbo comes off, BMW renews every seal it touches. This kit is that seal list in one box: 30 pieces, so you only do the job once. Use it for a turbo-off leak repair, a replacement turbo or a bigger turbo.

FAQ
- Can I replace the turbo line O-rings without pulling the turbo? BMW says the oil feed line can only be replaced with the turbo out. BMW's N55 text does not say that about the oil return or coolant lines, so get the steps for your car by VIN. This kit is the full set for when the turbo comes off.
- Does it fit a big turbo upgrade? It covers the factory joints: lines, manifold to head and turbo to downpipe. Check your upgrade's own instructions for anything extra it needs.
- How do I confirm it fits my car? Send us your 17-digit VIN before you order and we will confirm fit.
