SneedSpeed N18 Cylinder Head Rebuild Kit

Restore your MINI Cooper N18 cylinder head with the SneedSpeed N18 Cylinder Head Rebuild Kit. Built specifically around the MINI N18 engine, this configurable kit gives you the parts needed to properly refresh or rebuild the cylinder head without buying components you don't need.

Standard Kit Includes

Valve Stem Seals — Included with Every Kit

New valve stem seals help control oil from entering the combustion chamber through the valve guides, helping reduce oil consumption, startup smoke, and carbon buildup.

Optional Components — Select What Your Rebuild Needs

The following components are optional and are not included unless selected when ordering:

• Valve Guides
  Replace worn valve guides to restore proper valve alignment and clearance. Excessive guide wear can contribute to oil consumption, poor valve sealing, and accelerated valve-train wear.

• Intake & Exhaust Valves
  Replacement intake and exhaust valves allow the cylinder head to be properly rebuilt when the original valves are worn, damaged, burned, or no longer suitable for reuse.

• MLS Head Gasket
  Multi-layer steel head gasket designed to provide a durable seal between the N18 cylinder head and engine block.

Build the N18 Head Kit You Need

Every kit starts with a complete set of valve stem seals.

From there, select the additional components required for your rebuild:

• Valve Guides

• Intake & Exhaust Valves

• MLS Head Gasket

For a basic cylinder head refresh, choose only the parts you need. For a more complete N18 cylinder head overhaul, select all available options.
