Mahle MS Piston Set 64-68 Por 911 2.0L 80mm Bore 66mm Strk 130mm Rod 22mm Pin 38.8cc 10.0CR Set of 6

Mahle is a well-known name in engine components, particularly for their high-performance pistons. This Mahle MS Piston Set is built for the classic Porsche 911 models from 1964-1968 with the 2.0L engine. If you're rebuilding the heart of your air-cooled Porsche, these pistons are designed to handle the demands of that iconic flat-six.

This set features pistons with an 80mm bore and a 66mm stroke, designed to work with a 130mm connecting rod and a 22mm wrist pin. The 38.8cc dish volume contributes to a 10.0:1 compression ratio, which is a solid bump over stock for improved power delivery without being overly aggressive for pump gas. These are forged pistons, meaning they start as a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast aluminum, making them ideal for engines that see spirited driving or require a higher compression ratio.

This is a complete set of six pistons, ready for installation in your 911's engine. Please note that this set is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
