Description

Replacement 1000 cc piston.

ONLY FOR NIKASIL CYLINDERS

Siebenrock 1000cc piston 9.5:1.

Fits all 1000cc Nikasil cylinders, including the original BMW cylinders.

At 9.5:1 compression, this kit is an excellent way to restore torque and HP to the low compression engines from 1981-on with parts that have less reciprocating mass for a smoother and more responsive engine.

To lower compression to 8.8:1 use one part number 11 11 1 335 650 base gasket under each cylinder.

Sold individually, for a set order quantity of two.

Kit Includes:

  • Moly coated lightweight 9.5:1 forged piston.
  • Lightweight high performance wrist pin.
  • Set of 2 pin clips.
  • Complete ring set compatible with Nikasil cylinders.

    Specify your cylinder type A, B or C (above) which is stamped at the base of your cylinder.
