The Mahle PowerPak Piston Set is specifically designed for the 2.5L 5-cylinder engines of VW and Audi, offering powerful reliability for both street and track use. These pistons are perfect for high-performance applications where high thermal loads and high engine speeds are the norm. The high-quality pistons are manufactured from an advanced aluminum-silicon alloy, ensuring excellent strength and durability under extreme conditions. The 82.5mm piston bore and a compression ratio of 9.3:1 make these pistons ideal for high-boost applications. Thanks to the hard-anodized ring lands and the innovative GRAFAL coating, this set significantly reduces friction between the piston and the wall, contributing to quieter operation and increased wear resistance. This coating also allows for tighter tolerances, resulting in lower noise levels and improved overall engine efficiency. The set also includes high-quality 22mm German steel wrist pins and threaded fasteners, ensuring an optimal combination of weight, strength, and durability. To utilize the full potential of these pistons, aftermarket connecting rods with a non-tapered 22mm small end are required. For a direct fit and outstanding performance, IE's Tuscan connecting rods (IERTVB1) are the ideal choice. These Mahle pistons are not only optimized for strength and performance but also designed to handle the unique challenges of direct fuel injection and turbocharging. With their long life and powerful performance, they are the perfect addition to any 2.5L engine build, whether you're riding on the street or the track.
