Original BMW Spark Plug Tube Seal for BMW E9x M3, E60 M5, and E63/E64 M6 S65 and S85 (2006–2013)

Original BMW spark plug tube 11-12-7-835-170, which BMW calls a spark plug pipe, seals the spark plug recess in the cylinder head to the valve cover on the S65 V8 and S85 V10 engines in the M3, M5, and M6. Each plug well needs a seal at the cover so that engine oil stays out of the well while the ignition coil reaches the plug. This piece weighs 19 g, and BMW has produced it since September 2004. BMW repair information allows reuse only when the rubber around the edges is undamaged. Replacing these tubes with every valve cover gasket job is strongly recommended.

Original BMW Parts carry a 24-month parts warranty.

BMW repair information recommends replacing these tubes with each valve cover gasket change. One part number serves both the V8 M3 and the V10 M5 and M6, which keeps ordering simple across the three cars. The tube is sold individually, so order one for each plug well you are replacing.

Common Questions

Can I reuse my spark plug tubes during a valve cover gasket job?
Only when the rubber edges are not compromised, but new tubes are strongly recommended at every valve cover gasket change.

Is the M3 tube the same as the M5 and M6 tube?
Yes. BMW uses this one number on the S65 and S85.
