ONLY FOR NIKASIL CYLINDERS
Siebenrock 1000cc pistons 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.
Specify your cylinder type A, B or C below which is stamped at the base of your cylinder.
