Mahle MS Piston Set 76-83 Por 911 3.0-3.3L 100mm BR 70.4mm Stk 127.8mm Rod 22mm Pin 35cc 9.8CR Set 6

Mahle is well-known for making solid engine components, and this piston set is a prime example of their work for performance builds. If you're rebuilding the engine in your 1976-1983 Porsche 911 with a 3.0L or 3.3L engine, these pistons are built to handle the demands of a performance application.

This set features a 100mm bore, which is a common size for these engines when looking for a bit more displacement or to refresh worn cylinders. The 9.8:1 compression ratio is a notable bump over stock, giving you improved power and responsiveness without going too extreme. Mahle uses forged aluminum for these pistons, a stronger material than cast aluminum, which means they can withstand higher cylinder pressures and temperatures often found in modified or performance engines. The set includes pistons, rings, wrist pins, and locks, all designed to work together for a complete engine rebuild. The wrist pin diameter is 22mm, and the rod length is 127.8mm, ensuring proper fitment with compatible connecting rods.

When rebuilding an engine of this caliber, using well-made components is key to reliability and performance. This Mahle piston set is designed to fit right and perform reliably, giving you the confidence to put your Porsche back on the road with a strong heart. Remember that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
