If anything defines the M6, it's this - the BMW Motorsports S38 engine. It's powerful, runs strong, sounds great, and looks the part. Aside general maintanence, I've applied a number of upgrades and improvements to it.


  • New parts include the radiator, water pump, radiator hoses, engine fan clutch and coolant reservoir
  • BMW recommended non-phosphorus anti-freeze is used.
  • A new heater valve was also installed.

  • A new oil pump was installed.
  • Synthetic oil is used.
  • The right motor mount was replaced.

  • The valves were adjusted.
  • A new upper chain tensioner rail was installed.
  • A Euro spec intake camshaft was installed.
  • The Motorsport exhaust cam sprocket was installed to improve the mid-range.
  • Magnacor spark plug wires and new spark plugs were installed.
  • The valve cover an air plenum was refinshed with black wrinkle paint.

  • The Euro spec M6 header was installed.
  • The output flanges on the header were modified to fit the stock USA center section.
  • The header is a work of art - especially after fresh ceramic coating. The primary pipes are bent from individual tube sections without multiple weld joints - very impressive work.

  • The original restrictive airlow meter was replaced with a custom designed MAF system. See details here. This improved throttle response and power.
  • A new fuel filter was installed.
  • New O-rings were installed on the intake plenum.
  • A custom fresh air intake was made and a K&N filter installed.
