The TPR-! cylinder head for the BMW mini is a ported head  that uses OEM stock size valves to maintain the bottom end power when off boost.

The TPR1 head is best suited to fast road, everyday use or for the occasional track day user.

MPG will be improved with the use of this head due to better gas flow where the engine is allowed to be under less stress and an improvement in the air fuel ratio will result in a much more fuel defendant engine increasing your MPG.

Mods normally used alongside the cylinder head include

  • Exhaust
  • Pulley
  • Cylinder Head
